Given numbers are 12,62,21,956

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 12,62,21,956 is 622356.

Find LCM of 12,62,21,956 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 1 x 31 x 7 x 239 = 622356

Therefore, the lowest common multiple of 12,62,21,956 is 622356.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

12 x 62 x 21 x 956 = 14936544

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

12 : 1, 2, 3, 4, 6, 12

62 : 1, 2, 31, 62

21 : 1, 3, 7, 21

956 : 1, 2, 4, 239, 478, 956

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 12,62,21,956, is 1.

Now, the common factors can be found like this.

12:2x 2x 3

62:2x 31

21:3x 7

956:2x 2x 239

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 14936544/(1x24)

LCM = 14936544/24

LCM = 622356

Thus, we can understand that the LCM of 12,62,21,956 is 622356.

Here are some samples of LCM of two or more Numbers calculations.
