Given numbers are 471,136,916,20

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

The LCM of 471,136,916,20 is 73344120.

Find LCM of 471,136,916,20 with Prime Factorization

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

2 x 2 x 471 x 34 x 229 x 5 = 73344120

Therefore, the lowest common multiple of 471,136,916,20 is 73344120.

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.

471 x 136 x 916 x 20 = 1173505920

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.

471 : 1, 3, 157, 471

136 : 1, 2, 4, 8, 17, 34, 68, 136

916 : 1, 2, 4, 229, 458, 916

20 : 1, 2, 4, 5, 10, 20

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 471,136,916,20, is 1.

Now, the common factors can be found like this.

471:3x 157

136:2x 2x 2x 17

916:2x 2x 229

20:2x 2x 5

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 2 = 16

Therefore, the value for common factors is 16.

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 = 1173505920/(1x16)

LCM = 1173505920/16

LCM = 73344120

Thus, we can understand that the LCM of 471,136,916,20 is 73344120.
