Given numbers are 127,470,641,638,970

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

The LCM of 127,470,641,638,970 is 1183919096470.

Find LCM of 127,470,641,638,970 with Prime Factorization

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

2 x 5 x 127 x 47 x 641 x 319 x 97 = 1183919096470

Therefore, the lowest common multiple of 127,470,641,638,970 is 1183919096470.

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.

127 x 470 x 641 x 638 x 970 = 23678381929400

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.

127 : 1, 127

470 : 1, 2, 5, 10, 47, 94, 235, 470

641 : 1, 641

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

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,470,641,638,970, is 1.

Now, the common factors can be found like this.

127:127

470:2x 5x 47

641:641

638:2x 11x 29

970:2x 5x 97

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 5 = 20

Therefore, the value for common factors is 20.

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 = 23678381929400/(1x20)

LCM = 23678381929400/20

LCM = 1183919096470

Thus, we can understand that the LCM of 127,470,641,638,970 is 1183919096470.
