Given numbers are 478,780,133,470

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

The LCM of 478,780,133,470 is 1165311420.

Find LCM of 478,780,133,470 with Prime Factorization

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

2 x 5 x 239 x 78 x 133 x 47 = 1165311420

Therefore, the lowest common multiple of 478,780,133,470 is 1165311420.

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 133 x 470 = 23306228400

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

133 : 1, 7, 19, 133

470 : 1, 2, 5, 10, 47, 94, 235, 470

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,780,133,470, is 1.

Now, the common factors can be found like this.

478:2x 239

780:2x 2x 3x 5x 13

133:7x 19

470:2x 5x 47

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 5 = 20

Therefore, the value for common factors is 20.

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 = 23306228400/(1x20)

LCM = 23306228400/20

LCM = 1165311420

Thus, we can understand that the LCM of 478,780,133,470 is 1165311420.
