Given numbers are 417,780,726,394

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

The LCM of 417,780,726,394 is 2584407540.

Find LCM of 417,780,726,394 with Prime Factorization

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

2 x 3 x 139 x 130 x 121 x 197 = 2584407540

Therefore, the lowest common multiple of 417,780,726,394 is 2584407540.

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.

417 x 780 x 726 x 394 = 93038671440

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.

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

726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,780,726,394, is 1.

Now, the common factors can be found like this.

417:3x 139

780:2x 2x 3x 5x 13

726:2x 3x 11x 11

394:2x 197

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 93038671440/(1x36)

LCM = 93038671440/36

LCM = 2584407540

Thus, we can understand that the LCM of 417,780,726,394 is 2584407540.
