Given numbers are 626,109,974,780

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

The LCM of 626,109,974,780 is 12959683620.

Find LCM of 626,109,974,780 with Prime Factorization

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

2 x 313 x 109 x 487 x 390 = 12959683620

Therefore, the lowest common multiple of 626,109,974,780 is 12959683620.

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.

626 x 109 x 974 x 780 = 51838734480

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.

626 : 1, 2, 313, 626

109 : 1, 109

974 : 1, 2, 487, 974

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 626,109,974,780, is 1.

Now, the common factors can be found like this.

626:2x 313

109:109

974:2x 487

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 2 = 4

Therefore, the value for common factors is 4.

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 = 51838734480/(1x4)

LCM = 51838734480/4

LCM = 12959683620

Thus, we can understand that the LCM of 626,109,974,780 is 12959683620.
