Given numbers are 642,364,677,793

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

The LCM of 642,364,677,793 is 4825306668.

Find LCM of 642,364,677,793 with Prime Factorization

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

2 x 13 x 321 x 14 x 677 x 61 = 4825306668

Therefore, the lowest common multiple of 642,364,677,793 is 4825306668.

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.

642 x 364 x 677 x 793 = 125457973368

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

677 : 1, 677

793 : 1, 13, 61, 793

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,364,677,793, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

364:2x 2x 7x 13

677:677

793:13x 61

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 125457973368/(1x26)

LCM = 125457973368/26

LCM = 4825306668

Thus, we can understand that the LCM of 642,364,677,793 is 4825306668.
