Given numbers are 664,991,165,242

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

The LCM of 664,991,165,242 is 1194313560.

Find LCM of 664,991,165,242 with Prime Factorization

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

2 x 11 x 332 x 991 x 15 x 11 = 1194313560

Therefore, the lowest common multiple of 664,991,165,242 is 1194313560.

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 991 x 165 x 242 = 26274898320

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

991 : 1, 991

165 : 1, 3, 5, 11, 15, 33, 55, 165

242 : 1, 2, 11, 22, 121, 242

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,991,165,242, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

991:991

165:3x 5x 11

242:2x 11x 11

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 26274898320/(1x22)

LCM = 26274898320/22

LCM = 1194313560

Thus, we can understand that the LCM of 664,991,165,242 is 1194313560.
