Given numbers are 161,249,878,620,916

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

The LCM of 161,249,878,620,916 is 2498716100580.

Find LCM of 161,249,878,620,916 with Prime Factorization

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

2 x 2 x 161 x 249 x 439 x 155 x 229 = 2498716100580

Therefore, the lowest common multiple of 161,249,878,620,916 is 2498716100580.

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 249 x 878 x 620 x 916 = 19989728804640

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

249 : 1, 3, 83, 249

878 : 1, 2, 439, 878

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

916 : 1, 2, 4, 229, 458, 916

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,249,878,620,916, is 1.

Now, the common factors can be found like this.

161:7x 23

249:3x 83

878:2x 439

620:2x 2x 5x 31

916:2x 2x 229

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 = 19989728804640/(1x8)

LCM = 19989728804640/8

LCM = 2498716100580

Thus, we can understand that the LCM of 161,249,878,620,916 is 2498716100580.
