Given numbers are 631,689,654,436

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

The LCM of 631,689,654,436 is 568664772.

Find LCM of 631,689,654,436 with Prime Factorization

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

2 x 109 x 631 x 689 x 3 x 2 = 568664772

Therefore, the lowest common multiple of 631,689,654,436 is 568664772.

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.

631 x 689 x 654 x 436 = 123968920296

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.

631 : 1, 631

689 : 1, 13, 53, 689

654 : 1, 2, 3, 6, 109, 218, 327, 654

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,689,654,436, is 1.

Now, the common factors can be found like this.

631:631

689:13x 53

654:2x 3x 109

436:2x 2x 109

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

2x 109 = 218

Therefore, the value for common factors is 218.

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 = 123968920296/(1x218)

LCM = 123968920296/218

LCM = 568664772

Thus, we can understand that the LCM of 631,689,654,436 is 568664772.
