Factors of 60 are {1,2,3,4,5,6,10,12,15,20,30,60} As one of the numbers is 7 less than the other, the difference of two numbers is 7 Among {1,2,3,4,5,6,10,12,15,20,30,60}, 3 & 10 and 5 & 12 are the only two pair of numbers whose difference is 7. But Least common multiple of 3 and 10 is 30.
How to find the least common multiple of 60 and 90?
Example: Find the least common multiple (LCM) of 60 and 90 using prime factorization. Step 1 – The prime factorization of 60 and 90 are: 60 = 2 × 2 × 3 × 5 and 90 = 2 × 3 × 3 × 5 Step 2 – The product of all the prime factors = 2 × 2 × 3 × 5 × 3 = 180.
How to find the least common multiple of 6?
Example: Find the least common multiple (LCM) of 6 and 15 using the common division method. Step 1 – 2 is the smallest prime number and it is a factor of 6. Write this prime number on the left of the two numbers. For each number in the right column, continue finding out prime numbers which are their factors.

Which is the least common multiple in this calculator?
Calculator Use The Least Common Multiple (LCM) is also referred to as the Lowest Common Multiple (LCM) and Least Common Divisor (LCD). For two integers a and b, denoted LCM (a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM (2,3) = 6 and LCM (6,10) = 30.
Which is the lowest common multiple of 30?
You would normally multiply 30 by the remaining prime factors of 3, but there are no remaining prime factors. The lowest common multiple is 30. If one number is prime, and the other number’s prime factors include that prime number, the lowest common multiple will be equal to the non-prime number.
