Given numbers are 478,780,971,910

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

The LCM of 478,780,971,910 is 1267096740.

Find LCM of 478,780,971,910 with Prime Factorization

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

2 x 5 x 13 x 239 x 6 x 971 x 7 = 1267096740

Therefore, the lowest common multiple of 478,780,971,910 is 1267096740.

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.

478 x 780 x 971 x 910 = 329445152400

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.

478 : 1, 2, 239, 478

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

971 : 1, 971

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,780,971,910, is 1.

Now, the common factors can be found like this.

478:2x 239

780:2x 2x 3x 5x 13

971:971

910:2x 5x 7x 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 5x 13 = 260

Therefore, the value for common factors is 260.

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 = 329445152400/(1x260)

LCM = 329445152400/260

LCM = 1267096740

Thus, we can understand that the LCM of 478,780,971,910 is 1267096740.
