Given numbers are 623,446,309,780

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

The LCM of 623,446,309,780 is 11161555860.

Find LCM of 623,446,309,780 with Prime Factorization

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

2 x 3 x 623 x 223 x 103 x 130 = 11161555860

Therefore, the lowest common multiple of 623,446,309,780 is 11161555860.

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.

623 x 446 x 309 x 780 = 66969335160

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.

623 : 1, 7, 89, 623

446 : 1, 2, 223, 446

309 : 1, 3, 103, 309

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,446,309,780, is 1.

Now, the common factors can be found like this.

623:7x 89

446:2x 223

309:3x 103

780:2x 2x 3x 5x 13

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 66969335160/(1x6)

LCM = 66969335160/6

LCM = 11161555860

Thus, we can understand that the LCM of 623,446,309,780 is 11161555860.
