Given numbers are 521,535,428,669

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

The LCM of 521,535,428,669 is 745894860.

Find LCM of 521,535,428,669 with Prime Factorization

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

107 x 521 x 5 x 4 x 669 = 745894860

Therefore, the lowest common multiple of 521,535,428,669 is 745894860.

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 535 x 428 x 669 = 79810750020

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

535 : 1, 5, 107, 535

428 : 1, 2, 4, 107, 214, 428

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,535,428,669, is 1.

Now, the common factors can be found like this.

521:521

535:5x 107

428:2x 2x 107

669:3x 223

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

107 = 107

Therefore, the value for common factors is 107.

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 = 79810750020/(1x107)

LCM = 79810750020/107

LCM = 745894860

Thus, we can understand that the LCM of 521,535,428,669 is 745894860.
