lcm calculator least common multiple lcm also known as lowest common multiple or smallest common multiple is of two or more numbers is the smallest number which is exactly divisible by each one of the numbers lcm calculator is an online tool used for calculate the lcm of the given numbers it is a tool which makes calculations easy and fun if two numbers is given then it can easily calculate the lcm of that numbers steps for finding lcm step 1 express the given numbers as product of prime factors step 2 now take the prime numbers with highest power for all the prime numbers then the product of it gives the lcm for the given numbers example problems on lcm know more about decimal to fraction calculator
find the lcm for the 36 and 15 step 1 the prime factorization of 36 22 × 32 the prime factorization of 15 3 × 5 step 2 highest power of 2 in the set 22 highest power of 3 in the set 32 highest power of 5 in the set 5 so lcm 22 × 32 × 5 180 answer 180 2 find the lcm for the 72 and 24 step 1 the prime factorization of 72 23 × 32 the prime factorization of 24 23 × 3 step 2 highest power of 2 in the set 23 highest power of 3 in the set 32 so lcm 23 × 32 72 answer 72 learn more about square footage calculator

solution :let the unknown digit n the given number is then 700 80 n 780 n when reversed the new number is 100n 80 7 87 100n subtracting these two numbers we get after solving we get 693 99n the digit can be arranged in 3 ways or 6 ways we have already investigated 2 of these ways we can now try one of the remaining 4 ways one of these are n 95
100n 70 8 693 99n 199n 615 after solving we get n=3 answer the unknown digit is 3 college algebra word problem solver college algebra solvers help students to solve the word problems step by step they teach students how to understand the data given in the statement and solve for the value to be found out the online algebra tutors serve as free algebra solver who would help students in interpreting the word problems let us go over a few important math equivalents of english for numbers and algebra word problems so as to make the interpretation of word problems easier.
