Given numbers are 520,169,630,195,115

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

The LCM of 520,169,630,195,115 is 9795240.

Find LCM of 520,169,630,195,115 with Prime Factorization

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

2 x 3 x 5 x 13 x 4 x 1 x 21 x 13 x 23 = 9795240

Therefore, the lowest common multiple of 520,169,630,195,115 is 9795240.

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 169 x 630 x 195 x 115 = 1241546670000

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

169 : 1, 13, 169

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

195 : 1, 3, 5, 13, 15, 39, 65, 195

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,169,630,195,115, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

169:13x 13

630:2x 3x 3x 5x 7

195:3x 5x 13

115:5x 23

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

2x 3x 5x 5x 5x 13x 13 = 126750

Therefore, the value for common factors is 126750.

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 = 1241546670000/(1x126750)

LCM = 1241546670000/126750

LCM = 9795240

Thus, we can understand that the LCM of 520,169,630,195,115 is 9795240.
