Given numbers are 571,668,442,420

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

The LCM of 571,668,442,420 is 8851036740.

Find LCM of 571,668,442,420 with Prime Factorization

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

2 x 2 x 571 x 167 x 221 x 105 = 8851036740

Therefore, the lowest common multiple of 571,668,442,420 is 8851036740.

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.

571 x 668 x 442 x 420 = 70808293920

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.

571 : 1, 571

668 : 1, 2, 4, 167, 334, 668

442 : 1, 2, 13, 17, 26, 34, 221, 442

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 571,668,442,420, is 1.

Now, the common factors can be found like this.

571:571

668:2x 2x 167

442:2x 13x 17

420:2x 2x 3x 5x 7

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 = 70808293920/(1x8)

LCM = 70808293920/8

LCM = 8851036740

Thus, we can understand that the LCM of 571,668,442,420 is 8851036740.
