Given numbers are 520,209,207,851,665

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

The LCM of 520,209,207,851,665 is 5826660840.

Find LCM of 520,209,207,851,665 with Prime Factorization

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

5 x 19 x 23 x 104 x 11 x 9 x 37 x 7 = 5826660840

Therefore, the lowest common multiple of 520,209,207,851,665 is 5826660840.

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 209 x 207 x 851 x 665 = 12731253935400

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

209 : 1, 11, 19, 209

207 : 1, 3, 9, 23, 69, 207

851 : 1, 23, 37, 851

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,209,207,851,665, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

209:11x 19

207:3x 3x 23

851:23x 37

665:5x 7x 19

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

5x 19x 23 = 2185

Therefore, the value for common factors is 2185.

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 = 12731253935400/(1x2185)

LCM = 12731253935400/2185

LCM = 5826660840

Thus, we can understand that the LCM of 520,209,207,851,665 is 5826660840.
