Given numbers are 419,988,642,124

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

The LCM of 419,988,642,124 is 4119435372.

Find LCM of 419,988,642,124 with Prime Factorization

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

2 x 2 x 419 x 247 x 321 x 31 = 4119435372

Therefore, the lowest common multiple of 419,988,642,124 is 4119435372.

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.

419 x 988 x 642 x 124 = 32955482976

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.

419 : 1, 419

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

642 : 1, 2, 3, 6, 107, 214, 321, 642

124 : 1, 2, 4, 31, 62, 124

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,988,642,124, is 1.

Now, the common factors can be found like this.

419:419

988:2x 2x 13x 19

642:2x 3x 107

124:2x 2x 31

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 = 32955482976/(1x8)

LCM = 32955482976/8

LCM = 4119435372

Thus, we can understand that the LCM of 419,988,642,124 is 4119435372.
