Calculate the LCM of 521,123,772,396

Given numbers are 521,123,772,396

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

The LCM of 521,123,772,396 is 1632578508.

Find LCM of 521,123,772,396 with Prime Factorization


2 521, 123, 772, 396
2 521, 123, 386, 198
3 521, 123, 193, 99
521, 41, 193, 33

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

2 x 2 x 3 x 521 x 41 x 193 x 33 = 1632578508

Therefore, the lowest common multiple of 521,123,772,396 is 1632578508.

LCM Formula to Find Lowest Common Multiple of 521,123,772,396

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 123 x 772 x 396 = 19590942096

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

123 : 1, 3, 41, 123

772 : 1, 2, 4, 193, 386, 772

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,123,772,396, is 1.

Now, the common factors can be found like this.

521:521

123:3x 41

772:2x 2x 193

396:2x 2x 3x 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 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 19590942096/(1x12)

LCM = 19590942096/12

LCM = 1632578508

Thus, we can understand that the LCM of 521,123,772,396 is 1632578508.
