Given numbers are 221,715,554,808

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

The LCM of 221,715,554,808 is 2720483480.

Find LCM of 221,715,554,808 with Prime Factorization

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

2 x 13 x 17 x 55 x 277 x 404 = 2720483480

Therefore, the lowest common multiple of 221,715,554,808 is 2720483480.

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.

221 x 715 x 554 x 808 = 70732570480

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.

221 : 1, 13, 17, 221

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

554 : 1, 2, 277, 554

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,715,554,808, is 1.

Now, the common factors can be found like this.

221:13x 17

715:5x 11x 13

554:2x 277

808:2x 2x 2x 101

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 70732570480/(1x26)

LCM = 70732570480/26

LCM = 2720483480

Thus, we can understand that the LCM of 221,715,554,808 is 2720483480.
