Given numbers are 627,122,777,581

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

The LCM of 627,122,777,581 is 1644391518.

Find LCM of 627,122,777,581 with Prime Factorization

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

3 x 7 x 209 x 122 x 37 x 83 = 1644391518

Therefore, the lowest common multiple of 627,122,777,581 is 1644391518.

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.

627 x 122 x 777 x 581 = 34532221878

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.

627 : 1, 3, 11, 19, 33, 57, 209, 627

122 : 1, 2, 61, 122

777 : 1, 3, 7, 21, 37, 111, 259, 777

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,122,777,581, is 1.

Now, the common factors can be found like this.

627:3x 11x 19

122:2x 61

777:3x 7x 37

581:7x 83

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 34532221878/(1x21)

LCM = 34532221878/21

LCM = 1644391518

Thus, we can understand that the LCM of 627,122,777,581 is 1644391518.
