Given numbers are 581,506,620,681

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

The LCM of 581,506,620,681 is 62063384460.

Find LCM of 581,506,620,681 with Prime Factorization

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

2 x 581 x 253 x 310 x 681 = 62063384460

Therefore, the lowest common multiple of 581,506,620,681 is 62063384460.

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.

581 x 506 x 620 x 681 = 124126768920

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.

581 : 1, 7, 83, 581

506 : 1, 2, 11, 22, 23, 46, 253, 506

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,506,620,681, is 1.

Now, the common factors can be found like this.

581:7x 83

506:2x 11x 23

620:2x 2x 5x 31

681:3x 227

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

2 = 2

Therefore, the value for common factors is 2.

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 = 124126768920/(1x2)

LCM = 124126768920/2

LCM = 62063384460

Thus, we can understand that the LCM of 581,506,620,681 is 62063384460.
