Given numbers are 521,446,749,642

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

The LCM of 521,446,749,642 is 522126402.

Find LCM of 521,446,749,642 with Prime Factorization

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

2 x 107 x 521 x 223 x 7 x 3 = 522126402

Therefore, the lowest common multiple of 521,446,749,642 is 522126402.

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 446 x 749 x 642 = 111735050028

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

446 : 1, 2, 223, 446

749 : 1, 7, 107, 749

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,446,749,642, is 1.

Now, the common factors can be found like this.

521:521

446:2x 223

749:7x 107

642:2x 3x 107

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

2x 107 = 214

Therefore, the value for common factors is 214.

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 = 111735050028/(1x214)

LCM = 111735050028/214

LCM = 522126402

Thus, we can understand that the LCM of 521,446,749,642 is 522126402.
