Given numbers are 520,669,398,122

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

The LCM of 520,669,398,122 is 4222915320.

Find LCM of 520,669,398,122 with Prime Factorization

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

2 x 260 x 669 x 199 x 61 = 4222915320

Therefore, the lowest common multiple of 520,669,398,122 is 4222915320.

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.

520 x 669 x 398 x 122 = 16891661280

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

669 : 1, 3, 223, 669

398 : 1, 2, 199, 398

122 : 1, 2, 61, 122

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,669,398,122, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

669:3x 223

398:2x 199

122:2x 61

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 16891661280/(1x4)

LCM = 16891661280/4

LCM = 4222915320

Thus, we can understand that the LCM of 520,669,398,122 is 4222915320.
