Given numbers are 247,778,988,478

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

The LCM of 247,778,988,478 is 91855348.

Find LCM of 247,778,988,478 with Prime Factorization

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

2 x 13 x 19 x 1 x 389 x 2 x 239 = 91855348

Therefore, the lowest common multiple of 247,778,988,478 is 91855348.

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.

247 x 778 x 988 x 478 = 90753083824

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.

247 : 1, 13, 19, 247

778 : 1, 2, 389, 778

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,778,988,478, is 1.

Now, the common factors can be found like this.

247:13x 19

778:2x 389

988:2x 2x 13x 19

478:2x 239

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 13x 19 = 988

Therefore, the value for common factors is 988.

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 = 90753083824/(1x988)

LCM = 90753083824/988

LCM = 91855348

Thus, we can understand that the LCM of 247,778,988,478 is 91855348.
