Given numbers are 677,642,130,344

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

The LCM of 677,642,130,344 is 4859208120.

Find LCM of 677,642,130,344 with Prime Factorization

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

2 x 677 x 321 x 65 x 172 = 4859208120

Therefore, the lowest common multiple of 677,642,130,344 is 4859208120.

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.

677 x 642 x 130 x 344 = 19436832480

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.

677 : 1, 677

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

130 : 1, 2, 5, 10, 13, 26, 65, 130

344 : 1, 2, 4, 8, 43, 86, 172, 344

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,642,130,344, is 1.

Now, the common factors can be found like this.

677:677

642:2x 3x 107

130:2x 5x 13

344:2x 2x 2x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 19436832480/(1x4)

LCM = 19436832480/4

LCM = 4859208120

Thus, we can understand that the LCM of 677,642,130,344 is 4859208120.
