Given numbers are 161,986,493,355,117

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

The LCM of 161,986,493,355,117 is 6593515110.

Find LCM of 161,986,493,355,117 with Prime Factorization

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

17 x 29 x 161 x 2 x 1 x 355 x 117 = 6593515110

Therefore, the lowest common multiple of 161,986,493,355,117 is 6593515110.

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 986 x 493 x 355 x 117 = 3250602949230

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

986 : 1, 2, 17, 29, 34, 58, 493, 986

493 : 1, 17, 29, 493

355 : 1, 5, 71, 355

117 : 1, 3, 9, 13, 39, 117

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,986,493,355,117, is 1.

Now, the common factors can be found like this.

161:7x 23

986:2x 17x 29

493:17x 29

355:5x 71

117:3x 3x 13

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

17x 29 = 493

Therefore, the value for common factors is 493.

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 = 3250602949230/(1x493)

LCM = 3250602949230/493

LCM = 6593515110

Thus, we can understand that the LCM of 161,986,493,355,117 is 6593515110.
