Given numbers are 129,380,974,728

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

The LCM of 129,380,974,728 is 4344838680.

Find LCM of 129,380,974,728 with Prime Factorization

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

2 x 2 x 129 x 95 x 487 x 182 = 4344838680

Therefore, the lowest common multiple of 129,380,974,728 is 4344838680.

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.

129 x 380 x 974 x 728 = 34758709440

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.

129 : 1, 3, 43, 129

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

974 : 1, 2, 487, 974

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,380,974,728, is 1.

Now, the common factors can be found like this.

129:3x 43

380:2x 2x 5x 19

974:2x 487

728:2x 2x 2x 7x 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 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 34758709440/(1x8)

LCM = 34758709440/8

LCM = 4344838680

Thus, we can understand that the LCM of 129,380,974,728 is 4344838680.
