Given numbers are 381,579,965,613,646

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

The LCM of 381,579,965,613,646 is 145594604670.

Find LCM of 381,579,965,613,646 with Prime Factorization

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

3 x 193 x 127 x 1 x 5 x 613 x 646 = 145594604670

Therefore, the lowest common multiple of 381,579,965,613,646 is 145594604670.

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.

381 x 579 x 965 x 613 x 646 = 84299276103930

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.

381 : 1, 3, 127, 381

579 : 1, 3, 193, 579

965 : 1, 5, 193, 965

613 : 1, 613

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,579,965,613,646, is 1.

Now, the common factors can be found like this.

381:3x 127

579:3x 193

965:5x 193

613:613

646:2x 17x 19

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

3x 193 = 579

Therefore, the value for common factors is 579.

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 = 84299276103930/(1x579)

LCM = 84299276103930/579

LCM = 145594604670

Thus, we can understand that the LCM of 381,579,965,613,646 is 145594604670.
