Given numbers are 446,669,421,580

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

The LCM of 446,669,421,580 is 163356420.

Find LCM of 446,669,421,580 with Prime Factorization

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

2 x 223 x 1 x 3 x 421 x 290 = 163356420

Therefore, the lowest common multiple of 446,669,421,580 is 163356420.

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.

446 x 669 x 421 x 580 = 72856963320

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.

446 : 1, 2, 223, 446

669 : 1, 3, 223, 669

421 : 1, 421

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,669,421,580, is 1.

Now, the common factors can be found like this.

446:2x 223

669:3x 223

421:421

580:2x 2x 5x 29

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

2x 223 = 446

Therefore, the value for common factors is 446.

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 = 72856963320/(1x446)

LCM = 72856963320/446

LCM = 163356420

Thus, we can understand that the LCM of 446,669,421,580 is 163356420.
