Given numbers are 428,725,908,121

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

The LCM of 428,725,908,121 is 8523010100.

Find LCM of 428,725,908,121 with Prime Factorization

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

2 x 2 x 107 x 725 x 227 x 121 = 8523010100

Therefore, the lowest common multiple of 428,725,908,121 is 8523010100.

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.

428 x 725 x 908 x 121 = 34092040400

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.

428 : 1, 2, 4, 107, 214, 428

725 : 1, 5, 25, 29, 145, 725

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

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,725,908,121, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

725:5x 5x 29

908:2x 2x 227

121:11x 11

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 = 34092040400/(1x4)

LCM = 34092040400/4

LCM = 8523010100

Thus, we can understand that the LCM of 428,725,908,121 is 8523010100.
