Given numbers are 636,642,715,561,154

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

The LCM of 636,642,715,561,154 is 5790204420.

Find LCM of 636,642,715,561,154 with Prime Factorization

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

2 x 3 x 11 x 106 x 107 x 65 x 17 x 7 = 5790204420

Therefore, the lowest common multiple of 636,642,715,561,154 is 5790204420.

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 642 x 715 x 561 x 154 = 25222130453520

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

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

715 : 1, 5, 11, 13, 55, 65, 143, 715

561 : 1, 3, 11, 17, 33, 51, 187, 561

154 : 1, 2, 7, 11, 14, 22, 77, 154

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,642,715,561,154, is 1.

Now, the common factors can be found like this.

636:2x 2x 3x 53

642:2x 3x 107

715:5x 11x 13

561:3x 11x 17

154:2x 7x 11

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 3x 3x 11x 11 = 4356

Therefore, the value for common factors is 4356.

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 = 25222130453520/(1x4356)

LCM = 25222130453520/4356

LCM = 5790204420

Thus, we can understand that the LCM of 636,642,715,561,154 is 5790204420.
