Given numbers are 221,104,664,965

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

The LCM of 221,104,664,965 is 141607960.

Find LCM of 221,104,664,965 with Prime Factorization

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

2 x 2 x 2 x 13 x 17 x 1 x 83 x 965 = 141607960

Therefore, the lowest common multiple of 221,104,664,965 is 141607960.

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.

221 x 104 x 664 x 965 = 14727227840

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.

221 : 1, 13, 17, 221

104 : 1, 2, 4, 8, 13, 26, 52, 104

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

965 : 1, 5, 193, 965

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,104,664,965, is 1.

Now, the common factors can be found like this.

221:13x 17

104:2x 2x 2x 13

664:2x 2x 2x 83

965:5x 193

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 13 = 104

Therefore, the value for common factors is 104.

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 = 14727227840/(1x104)

LCM = 14727227840/104

LCM = 141607960

Thus, we can understand that the LCM of 221,104,664,965 is 141607960.
