Given numbers are 557,720,163,169,394

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

The LCM of 557,720,163,169,394 is 2176347429360.

Find LCM of 557,720,163,169,394 with Prime Factorization

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

2 x 557 x 360 x 163 x 169 x 197 = 2176347429360

Therefore, the lowest common multiple of 557,720,163,169,394 is 2176347429360.

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.

557 x 720 x 163 x 169 x 394 = 4352694858720

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.

557 : 1, 557

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

163 : 1, 163

169 : 1, 13, 169

394 : 1, 2, 197, 394

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,720,163,169,394, is 1.

Now, the common factors can be found like this.

557:557

720:2x 2x 2x 2x 3x 3x 5

163:163

169:13x 13

394:2x 197

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

2 = 2

Therefore, the value for common factors is 2.

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 = 4352694858720/(1x2)

LCM = 4352694858720/2

LCM = 2176347429360

Thus, we can understand that the LCM of 557,720,163,169,394 is 2176347429360.
