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.
Which is the least common multiple of two numbers?
For example, LCM (2,3) = 6 and LCM (6,10) = 30. For the least common multiple of more than 2 numbers, say a, b, c and d, it is the smallest integer that is evenly divisible by all numbers and can be calculated such that LCM (a,b,c,d) = LCM ( LCM ( LCM ( a,b ), c ), d ).
How to calculate the LCM of two numbers?
To calculate the LCM of the two numbers “A” and ” B” by using listing out the common multiples follow the steps given below: 1 List a few multiples of A and B 2 Mark the common multiples from the multiples of both numbers. 3 Select the smallest common multiple, that smallest common multiple is the LCM of the two numbers.
