Given numbers are 644,840,129,436,267

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

The LCM of 644,840,129,436,267 is 8059202760.

Find LCM of 644,840,129,436,267 with Prime Factorization

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

2 x 2 x 3 x 7 x 23 x 10 x 43 x 109 x 89 = 8059202760

Therefore, the lowest common multiple of 644,840,129,436,267 is 8059202760.

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.

644 x 840 x 129 x 436 x 267 = 8123676382080

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

129 : 1, 3, 43, 129

436 : 1, 2, 4, 109, 218, 436

267 : 1, 3, 89, 267

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,840,129,436,267, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

840:2x 2x 2x 3x 5x 7

129:3x 43

436:2x 2x 109

267:3x 89

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 3x 3x 7 = 1008

Therefore, the value for common factors is 1008.

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 = 8123676382080/(1x1008)

LCM = 8123676382080/1008

LCM = 8059202760

Thus, we can understand that the LCM of 644,840,129,436,267 is 8059202760.
