Given numbers are 908,720,471,392

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

The LCM of 908,720,471,392 is 1257343920.

Find LCM of 908,720,471,392 with Prime Factorization

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

2 x 2 x 2 x 3 x 227 x 30 x 157 x 49 = 1257343920

Therefore, the lowest common multiple of 908,720,471,392 is 1257343920.

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.

908 x 720 x 471 x 392 = 120705016320

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.

908 : 1, 2, 4, 227, 454, 908

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

471 : 1, 3, 157, 471

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 908,720,471,392, is 1.

Now, the common factors can be found like this.

908:2x 2x 227

720:2x 2x 2x 2x 3x 3x 5

471:3x 157

392:2x 2x 2x 7x 7

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 3 = 96

Therefore, the value for common factors is 96.

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 = 120705016320/(1x96)

LCM = 120705016320/96

LCM = 1257343920

Thus, we can understand that the LCM of 908,720,471,392 is 1257343920.
