Given numbers are 257,520,797,624

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

The LCM of 257,520,797,624 is 639066480.

Find LCM of 257,520,797,624 with Prime Factorization

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

2 x 2 x 2 x 13 x 257 x 5 x 797 x 6 = 639066480

Therefore, the lowest common multiple of 257,520,797,624 is 639066480.

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 520 x 797 x 624 = 66462913920

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

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

797 : 1, 797

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,520,797,624, is 1.

Now, the common factors can be found like this.

257:257

520:2x 2x 2x 5x 13

797:797

624:2x 2x 2x 2x 3x 13

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 13 = 104

Therefore, the value for common factors is 104.

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 = 66462913920/(1x104)

LCM = 66462913920/104

LCM = 639066480

Thus, we can understand that the LCM of 257,520,797,624 is 639066480.
