Given numbers are 257,104,642,398,995

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

The LCM of 257,104,642,398,995 is 8536789560.

Find LCM of 257,104,642,398,995 with Prime Factorization

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

2 x 199 x 257 x 52 x 321 x 1 x 5 = 8536789560

Therefore, the lowest common multiple of 257,104,642,398,995 is 8536789560.

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.

257 x 104 x 642 x 398 x 995 = 6795284489760

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.

257 : 1, 257

104 : 1, 2, 4, 8, 13, 26, 52, 104

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

398 : 1, 2, 199, 398

995 : 1, 5, 199, 995

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,104,642,398,995, is 1.

Now, the common factors can be found like this.

257:257

104:2x 2x 2x 13

642:2x 3x 107

398:2x 199

995:5x 199

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 199 = 796

Therefore, the value for common factors is 796.

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 = 6795284489760/(1x796)

LCM = 6795284489760/796

LCM = 8536789560

Thus, we can understand that the LCM of 257,104,642,398,995 is 8536789560.
