Given numbers are 257,654,960,620

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

The LCM of 257,654,960,620 is 833666880.

Find LCM of 257,654,960,620 with Prime Factorization

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

2 x 2 x 3 x 5 x 257 x 109 x 16 x 31 = 833666880

Therefore, the lowest common multiple of 257,654,960,620 is 833666880.

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 654 x 960 x 620 = 100040025600

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

654 : 1, 2, 3, 6, 109, 218, 327, 654

960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,654,960,620, is 1.

Now, the common factors can be found like this.

257:257

654:2x 3x 109

960:2x 2x 2x 2x 2x 2x 3x 5

620:2x 2x 5x 31

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 3x 5 = 120

Therefore, the value for common factors is 120.

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 = 100040025600/(1x120)

LCM = 100040025600/120

LCM = 833666880

Thus, we can understand that the LCM of 257,654,960,620 is 833666880.
