Given numbers are 722,621,638,681

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

The LCM of 722,621,638,681 is 32467237506.

Find LCM of 722,621,638,681 with Prime Factorization

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

2 x 3 x 361 x 207 x 319 x 227 = 32467237506

Therefore, the lowest common multiple of 722,621,638,681 is 32467237506.

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.

722 x 621 x 638 x 681 = 194803425036

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.

722 : 1, 2, 19, 38, 361, 722

621 : 1, 3, 9, 23, 27, 69, 207, 621

638 : 1, 2, 11, 22, 29, 58, 319, 638

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,621,638,681, is 1.

Now, the common factors can be found like this.

722:2x 19x 19

621:3x 3x 3x 23

638:2x 11x 29

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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 194803425036/(1x6)

LCM = 194803425036/6

LCM = 32467237506

Thus, we can understand that the LCM of 722,621,638,681 is 32467237506.
