Given numbers are 664,956,372,420,988

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

The LCM of 664,956,372,420,988 is 127589203560.

Find LCM of 664,956,372,420,988 with Prime Factorization

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

2 x 2 x 3 x 166 x 239 x 31 x 35 x 247 = 127589203560

Therefore, the lowest common multiple of 664,956,372,420,988 is 127589203560.

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.

664 x 956 x 372 x 420 x 988 = 97988508334080

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

956 : 1, 2, 4, 239, 478, 956

372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,956,372,420,988, is 4.

Now, the common factors can be found like this.

664:2x 2x 2x 83

956:2x 2x 239

372:2x 2x 3x 31

420:2x 2x 3x 5x 7

988:2x 2x 13x 19

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 2x 2x 2x 3 = 192

Therefore, the value for common factors is 192.

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 = 97988508334080/(4x192)

LCM = 97988508334080/768

LCM = 127589203560

Thus, we can understand that the LCM of 664,956,372,420,988 is 127589203560.
