Given numbers are 521,702,415,528

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

The LCM of 521,702,415,528 is 13356897840.

Find LCM of 521,702,415,528 with Prime Factorization

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

2 x 3 x 521 x 117 x 415 x 88 = 13356897840

Therefore, the lowest common multiple of 521,702,415,528 is 13356897840.

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.

521 x 702 x 415 x 528 = 80141387040

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.

521 : 1, 521

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

415 : 1, 5, 83, 415

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,702,415,528, is 1.

Now, the common factors can be found like this.

521:521

702:2x 3x 3x 3x 13

415:5x 83

528:2x 2x 2x 2x 3x 11

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 80141387040/(1x6)

LCM = 80141387040/6

LCM = 13356897840

Thus, we can understand that the LCM of 521,702,415,528 is 13356897840.
