Given numbers are 636,555,767,642

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

The LCM of 636,555,767,642 is 9656238540.

Find LCM of 636,555,767,642 with Prime Factorization

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

2 x 3 x 106 x 185 x 767 x 107 = 9656238540

Therefore, the lowest common multiple of 636,555,767,642 is 9656238540.

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.

636 x 555 x 767 x 642 = 173812293720

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.

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

555 : 1, 3, 5, 15, 37, 111, 185, 555

767 : 1, 13, 59, 767

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,555,767,642, is 1.

Now, the common factors can be found like this.

636:2x 2x 3x 53

555:3x 5x 37

767:13x 59

642:2x 3x 107

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 173812293720/(1x18)

LCM = 173812293720/18

LCM = 9656238540

Thus, we can understand that the LCM of 636,555,767,642 is 9656238540.
