Given numbers are 478,138,665,537

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

The LCM of 478,138,665,537 is 3926012370.

Find LCM of 478,138,665,537 with Prime Factorization

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

2 x 3 x 239 x 23 x 665 x 179 = 3926012370

Therefore, the lowest common multiple of 478,138,665,537 is 3926012370.

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 138 x 665 x 537 = 23556074220

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

665 : 1, 5, 7, 19, 35, 95, 133, 665

537 : 1, 3, 179, 537

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,138,665,537, is 1.

Now, the common factors can be found like this.

478:2x 239

138:2x 3x 23

665:5x 7x 19

537:3x 179

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 23556074220/(1x6)

LCM = 23556074220/6

LCM = 3926012370

Thus, we can understand that the LCM of 478,138,665,537 is 3926012370.
