Given numbers are 436,129,946,721

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

The LCM of 436,129,946,721 is 446071164.

Find LCM of 436,129,946,721 with Prime Factorization

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

2 x 43 x 218 x 3 x 11 x 721 = 446071164

Therefore, the lowest common multiple of 436,129,946,721 is 446071164.

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.

436 x 129 x 946 x 721 = 38362120104

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.

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

129 : 1, 3, 43, 129

946 : 1, 2, 11, 22, 43, 86, 473, 946

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,129,946,721, is 1.

Now, the common factors can be found like this.

436:2x 2x 109

129:3x 43

946:2x 11x 43

721:7x 103

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

2x 43 = 86

Therefore, the value for common factors is 86.

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 = 38362120104/(1x86)

LCM = 38362120104/86

LCM = 446071164

Thus, we can understand that the LCM of 436,129,946,721 is 446071164.
