Given numbers are 156,706,840,431,780

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

The LCM of 156,706,840,431,780 is 1661401560.

Find LCM of 156,706,840,431,780 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 1 x 353 x 14 x 431 x 1 = 1661401560

Therefore, the lowest common multiple of 156,706,840,431,780 is 1661401560.

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.

156 x 706 x 840 x 431 x 780 = 31101437203200

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.

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

706 : 1, 2, 353, 706

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

431 : 1, 431

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,706,840,431,780, is 1.

Now, the common factors can be found like this.

156:2x 2x 3x 13

706:2x 353

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

431:431

780:2x 2x 3x 5x 13

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 2x 3x 3x 5x 13 = 18720

Therefore, the value for common factors is 18720.

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 = 31101437203200/(1x18720)

LCM = 31101437203200/18720

LCM = 1661401560

Thus, we can understand that the LCM of 156,706,840,431,780 is 1661401560.
