Given numbers are 321,782,756,407,430

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

The LCM of 321,782,756,407,430 is 2767675693860.

Find LCM of 321,782,756,407,430 with Prime Factorization

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

2 x 3 x 107 x 391 x 126 x 407 x 215 = 2767675693860

Therefore, the lowest common multiple of 321,782,756,407,430 is 2767675693860.

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.

321 x 782 x 756 x 407 x 430 = 33212108326320

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.

321 : 1, 3, 107, 321

782 : 1, 2, 17, 23, 34, 46, 391, 782

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

407 : 1, 11, 37, 407

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,782,756,407,430, is 1.

Now, the common factors can be found like this.

321:3x 107

782:2x 17x 23

756:2x 2x 3x 3x 3x 7

407:11x 37

430:2x 5x 43

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 = 33212108326320/(1x12)

LCM = 33212108326320/12

LCM = 2767675693860

Thus, we can understand that the LCM of 321,782,756,407,430 is 2767675693860.
