Given numbers are 520,805,506,860,129

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

The LCM of 520,805,506,860,129 is 118798680.

Find LCM of 520,805,506,860,129 with Prime Factorization

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

2 x 2 x 5 x 23 x 43 x 26 x 7 x 11 x 1 x 3 = 118798680

Therefore, the lowest common multiple of 520,805,506,860,129 is 118798680.

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 805 x 506 x 860 x 129 = 23498378904000

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

805 : 1, 5, 7, 23, 35, 115, 161, 805

506 : 1, 2, 11, 22, 23, 46, 253, 506

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

129 : 1, 3, 43, 129

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,805,506,860,129, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

805:5x 7x 23

506:2x 11x 23

860:2x 2x 5x 43

129:3x 43

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 2x 5x 5x 23x 43 = 197800

Therefore, the value for common factors is 197800.

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 = 23498378904000/(1x197800)

LCM = 23498378904000/197800

LCM = 118798680

Thus, we can understand that the LCM of 520,805,506,860,129 is 118798680.
