Given numbers are 646,986,814,430,456

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

The LCM of 646,986,814,430,456 is 19671824040.

Find LCM of 646,986,814,430,456 with Prime Factorization

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

2 x 17 x 19 x 1 x 29 x 407 x 215 x 12 = 19671824040

Therefore, the lowest common multiple of 646,986,814,430,456 is 19671824040.

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.

646 x 986 x 814 x 430 x 456 = 101663986638720

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.

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

986 : 1, 2, 17, 29, 34, 58, 493, 986

814 : 1, 2, 11, 22, 37, 74, 407, 814

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

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,986,814,430,456, is 2.

Now, the common factors can be found like this.

646:2x 17x 19

986:2x 17x 29

814:2x 11x 37

430:2x 5x 43

456:2x 2x 2x 3x 19

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 2x 17x 19 = 2584

Therefore, the value for common factors is 2584.

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 = 101663986638720/(2x2584)

LCM = 101663986638720/5168

LCM = 19671824040

Thus, we can understand that the LCM of 646,986,814,430,456 is 19671824040.
