The LCM of 14 and 42 is 42.
The simplest method to determine the least common multiple in this case is to notice that 42 is a multiple of 14. Since 42 is a multiple of 14, the least common multiple is 42.
To determine the least common multiple of two numbers, you can also determine the prime factors of both numbers. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor).
The prime factors of 14 are 2 and 7.
The prime factors of 42 are 2, 3, and 7.
The greatest common factor of 14 and 42 is 14.
So, the least common multiple of 14 and 42 is (2x7) x (2x3x7) ÷ 14 = 42.

What is the least common multiple of 14 and 21?
The least common multiple of 14 and 21 is 42.Look at the multiples of 14. They are 14, 28 and 42.Now clearly 14 and 28 are can't be multiples of 21 also so throw them out as candidate for the LCM. However, the next number. 42 is 21x2.We know there is no smaller common multiple because 21x1 did not work so we are done.The LCM is: 42
