Given numbers are 520,286,702,208

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

The LCM of 520,286,702,208 is 308880.

Find LCM of 520,286,702,208 with Prime Factorization

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

2 x 2 x 2 x 13 x 5 x 11 x 27 x 2 = 308880

Therefore, the lowest common multiple of 520,286,702,208 is 308880.

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 286 x 702 x 208 = 21715499520

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

286 : 1, 2, 11, 13, 22, 26, 143, 286

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

26 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,286,702,208, is 26.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

286:2x 11x 13

702:2x 3x 3x 3x 13

208:2x 2x 2x 2x 13

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 2x 13x 13 = 2704

Therefore, the value for common factors is 2704.

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 = 21715499520/(26x2704)

LCM = 21715499520/70304

LCM = 308880

Thus, we can understand that the LCM of 520,286,702,208 is 308880.
