Given numbers are 157,665,489,396,471

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

The LCM of 157,665,489,396,471 is 6739133940.

Find LCM of 157,665,489,396,471 with Prime Factorization

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

3 x 157 x 1 x 665 x 163 x 132 x 1 = 6739133940

Therefore, the lowest common multiple of 157,665,489,396,471 is 6739133940.

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.

157 x 665 x 489 x 396 x 471 = 9522396257220

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.

157 : 1, 157

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

489 : 1, 3, 163, 489

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

471 : 1, 3, 157, 471

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,665,489,396,471, is 1.

Now, the common factors can be found like this.

157:157

665:5x 7x 19

489:3x 163

396:2x 2x 3x 3x 11

471:3x 157

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

3x 3x 157 = 1413

Therefore, the value for common factors is 1413.

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 = 9522396257220/(1x1413)

LCM = 9522396257220/1413

LCM = 6739133940

Thus, we can understand that the LCM of 157,665,489,396,471 is 6739133940.
