Given numbers are 780,643,583,374

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

The LCM of 780,643,583,374 is 4970762940.

Find LCM of 780,643,583,374 with Prime Factorization

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

2 x 11 x 390 x 643 x 53 x 17 = 4970762940

Therefore, the lowest common multiple of 780,643,583,374 is 4970762940.

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.

780 x 643 x 583 x 374 = 109356784680

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.

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

643 : 1, 643

583 : 1, 11, 53, 583

374 : 1, 2, 11, 17, 22, 34, 187, 374

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,643,583,374, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

643:643

583:11x 53

374:2x 11x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 109356784680/(1x22)

LCM = 109356784680/22

LCM = 4970762940

Thus, we can understand that the LCM of 780,643,583,374 is 4970762940.
