Given numbers are 461,169,436,646

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

The LCM of 461,169,436,646 is 10971768652.

Find LCM of 461,169,436,646 with Prime Factorization

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

2 x 461 x 169 x 218 x 323 = 10971768652

Therefore, the lowest common multiple of 461,169,436,646 is 10971768652.

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.

461 x 169 x 436 x 646 = 21943537304

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.

461 : 1, 461

169 : 1, 13, 169

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,169,436,646, is 1.

Now, the common factors can be found like this.

461:461

169:13x 13

436:2x 2x 109

646:2x 17x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 21943537304/(1x2)

LCM = 21943537304/2

LCM = 10971768652

Thus, we can understand that the LCM of 461,169,436,646 is 10971768652.
