Given numbers are 521,699,363,390

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

The LCM of 521,699,363,390 is 5728535670.

Find LCM of 521,699,363,390 with Prime Factorization

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

3 x 521 x 233 x 121 x 130 = 5728535670

Therefore, the lowest common multiple of 521,699,363,390 is 5728535670.

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 699 x 363 x 390 = 51556821030

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

699 : 1, 3, 233, 699

363 : 1, 3, 11, 33, 121, 363

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,699,363,390, is 1.

Now, the common factors can be found like this.

521:521

699:3x 233

363:3x 11x 11

390:2x 3x 5x 13

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 51556821030/(1x9)

LCM = 51556821030/9

LCM = 5728535670

Thus, we can understand that the LCM of 521,699,363,390 is 5728535670.
