Given numbers are 161,648,754,836

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

The LCM of 161,648,754,836 is 8220316104.

Find LCM of 161,648,754,836 with Prime Factorization

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

2 x 2 x 161 x 162 x 377 x 209 = 8220316104

Therefore, the lowest common multiple of 161,648,754,836 is 8220316104.

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.

161 x 648 x 754 x 836 = 65762528832

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.

161 : 1, 7, 23, 161

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

754 : 1, 2, 13, 26, 29, 58, 377, 754

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,648,754,836, is 1.

Now, the common factors can be found like this.

161:7x 23

648:2x 2x 2x 3x 3x 3x 3

754:2x 13x 29

836:2x 2x 11x 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 2 = 8

Therefore, the value for common factors is 8.

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 = 65762528832/(1x8)

LCM = 65762528832/8

LCM = 8220316104

Thus, we can understand that the LCM of 161,648,754,836 is 8220316104.
