Given numbers are 247,530,156,478

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

The LCM of 247,530,156,478 is 187724940.

Find LCM of 247,530,156,478 with Prime Factorization

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

2 x 13 x 19 x 265 x 6 x 239 = 187724940

Therefore, the lowest common multiple of 247,530,156,478 is 187724940.

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 530 x 156 x 478 = 9761696880

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

530 : 1, 2, 5, 10, 53, 106, 265, 530

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,530,156,478, is 1.

Now, the common factors can be found like this.

247:13x 19

530:2x 5x 53

156:2x 2x 3x 13

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 13 = 52

Therefore, the value for common factors is 52.

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 = 9761696880/(1x52)

LCM = 9761696880/52

LCM = 187724940

Thus, we can understand that the LCM of 247,530,156,478 is 187724940.
