Given numbers are 665,929,836,396,490

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

The LCM of 665,929,836,396,490 is 1712500020.

Find LCM of 665,929,836,396,490 with Prime Factorization

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

2 x 2 x 5 x 7 x 11 x 19 x 1 x 929 x 1 x 9 x 7 = 1712500020

Therefore, the lowest common multiple of 665,929,836,396,490 is 1712500020.

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.

665 x 929 x 836 x 396 x 490 = 100215501170400

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.

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

929 : 1, 929

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

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

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,929,836,396,490, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

929:929

836:2x 2x 11x 19

396:2x 2x 3x 3x 11

490:2x 5x 7x 7

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 2x 5x 7x 11x 19 = 58520

Therefore, the value for common factors is 58520.

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 = 100215501170400/(1x58520)

LCM = 100215501170400/58520

LCM = 1712500020

Thus, we can understand that the LCM of 665,929,836,396,490 is 1712500020.
