Given numbers are 641,506,156,638,736

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

The LCM of 641,506,156,638,736 is 5869365216.

Find LCM of 641,506,156,638,736 with Prime Factorization

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

2 x 2 x 11 x 23 x 641 x 1 x 39 x 29 x 8 = 5869365216

Therefore, the lowest common multiple of 641,506,156,638,736 is 5869365216.

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.

641 x 506 x 156 x 638 x 736 = 23759190394368

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.

641 : 1, 641

506 : 1, 2, 11, 22, 23, 46, 253, 506

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

638 : 1, 2, 11, 22, 29, 58, 319, 638

736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,506,156,638,736, is 1.

Now, the common factors can be found like this.

641:641

506:2x 11x 23

156:2x 2x 3x 13

638:2x 11x 29

736:2x 2x 2x 2x 2x 23

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 2x 11x 23 = 4048

Therefore, the value for common factors is 4048.

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 = 23759190394368/(1x4048)

LCM = 23759190394368/4048

LCM = 5869365216

Thus, we can understand that the LCM of 641,506,156,638,736 is 5869365216.
