Given numbers are 615,847,291,161

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

The LCM of 615,847,291,161 is 1162139055.

Find LCM of 615,847,291,161 with Prime Factorization

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

3 x 7 x 205 x 121 x 97 x 23 = 1162139055

Therefore, the lowest common multiple of 615,847,291,161 is 1162139055.

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.

615 x 847 x 291 x 161 = 24404920155

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.

615 : 1, 3, 5, 15, 41, 123, 205, 615

847 : 1, 7, 11, 77, 121, 847

291 : 1, 3, 97, 291

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,847,291,161, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

847:7x 11x 11

291:3x 97

161:7x 23

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 24404920155/(1x21)

LCM = 24404920155/21

LCM = 1162139055

Thus, we can understand that the LCM of 615,847,291,161 is 1162139055.
