Given numbers are 763,936,562,642

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

The LCM of 763,936,562,642 is 21472889256.

Find LCM of 763,936,562,642 with Prime Factorization

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

2 x 3 x 763 x 156 x 281 x 107 = 21472889256

Therefore, the lowest common multiple of 763,936,562,642 is 21472889256.

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.

763 x 936 x 562 x 642 = 257674671072

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.

763 : 1, 7, 109, 763

936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936

562 : 1, 2, 281, 562

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 763,936,562,642, is 1.

Now, the common factors can be found like this.

763:7x 109

936:2x 2x 2x 3x 3x 13

562:2x 281

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 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 257674671072/(1x12)

LCM = 257674671072/12

LCM = 21472889256

Thus, we can understand that the LCM of 763,936,562,642 is 21472889256.
