Given numbers are 144,639,137,779,961

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

The LCM of 144,639,137,779,961 is 1048581649872.

Find LCM of 144,639,137,779,961 with Prime Factorization

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

3 x 3 x 16 x 71 x 137 x 779 x 961 = 1048581649872

Therefore, the lowest common multiple of 144,639,137,779,961 is 1048581649872.

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.

144 x 639 x 137 x 779 x 961 = 9437234848848

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.

144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144

639 : 1, 3, 9, 71, 213, 639

137 : 1, 137

779 : 1, 19, 41, 779

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,639,137,779,961, is 1.

Now, the common factors can be found like this.

144:2x 2x 2x 2x 3x 3

639:3x 3x 71

137:137

779:19x 41

961:31x 31

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 9437234848848/(1x9)

LCM = 9437234848848/9

LCM = 1048581649872

Thus, we can understand that the LCM of 144,639,137,779,961 is 1048581649872.
