Given numbers are 418,572,142,923

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

The LCM of 418,572,142,923 is 771628.

Find LCM of 418,572,142,923 with Prime Factorization

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

2 x 11 x 13 x 71 x 19 x 2 x 1 x 1 = 771628

Therefore, the lowest common multiple of 418,572,142,923 is 771628.

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.

418 x 572 x 142 x 923 = 31337356336

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

142 : 1, 2, 71, 142

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,572,142,923, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

572:2x 2x 11x 13

142:2x 71

923:13x 71

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 11x 13x 71 = 40612

Therefore, the value for common factors is 40612.

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 = 31337356336/(1x40612)

LCM = 31337356336/40612

LCM = 771628

Thus, we can understand that the LCM of 418,572,142,923 is 771628.
