Given numbers are 478,538,478,715

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

The LCM of 478,538,478,715 is 91936130.

Find LCM of 478,538,478,715 with Prime Factorization

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

2 x 239 x 1 x 269 x 1 x 715 = 91936130

Therefore, the lowest common multiple of 478,538,478,715 is 91936130.

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.

478 x 538 x 478 x 715 = 87890940280

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.

478 : 1, 2, 239, 478

538 : 1, 2, 269, 538

478 : 1, 2, 239, 478

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 478,538,478,715, is 1.

Now, the common factors can be found like this.

478:2x 239

538:2x 269

478:2x 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 2x 239 = 956

Therefore, the value for common factors is 956.

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 = 87890940280/(1x956)

LCM = 87890940280/956

LCM = 91936130

Thus, we can understand that the LCM of 478,538,478,715 is 91936130.
