Given numbers are 158,418,717,715

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

The LCM of 158,418,717,715 is 1538990310.

Find LCM of 158,418,717,715 with Prime Factorization

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

2 x 11 x 79 x 19 x 717 x 65 = 1538990310

Therefore, the lowest common multiple of 158,418,717,715 is 1538990310.

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.

158 x 418 x 717 x 715 = 33857786820

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.

158 : 1, 2, 79, 158

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

717 : 1, 3, 239, 717

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 158,418,717,715, is 1.

Now, the common factors can be found like this.

158:2x 79

418:2x 11x 19

717:3x 239

715:5x 11x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 33857786820/(1x22)

LCM = 33857786820/22

LCM = 1538990310

Thus, we can understand that the LCM of 158,418,717,715 is 1538990310.

Here are some samples of LCM of two or more Numbers calculations.
