Given numbers are 659,417,780,402

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

The LCM of 659,417,780,402 is 4787068260.

Find LCM of 659,417,780,402 with Prime Factorization

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

2 x 3 x 659 x 139 x 130 x 67 = 4787068260

Therefore, the lowest common multiple of 659,417,780,402 is 4787068260.

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.

659 x 417 x 780 x 402 = 86167228680

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.

659 : 1, 659

417 : 1, 3, 139, 417

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

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 659,417,780,402, is 1.

Now, the common factors can be found like this.

659:659

417:3x 139

780:2x 2x 3x 5x 13

402:2x 3x 67

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 86167228680/(1x18)

LCM = 86167228680/18

LCM = 4787068260

Thus, we can understand that the LCM of 659,417,780,402 is 4787068260.
