Calculate the LCM of 521,989,956,822,268

Given numbers are 521,989,956,822,268

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

The LCM of 521,989,956,822,268 is 13564648105068.

Find LCM of 521,989,956,822,268 with Prime Factorization


2 521, 989, 956, 822, 268
2 521, 989, 478, 411, 134
521, 989, 239, 411, 67

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

2 x 2 x 521 x 989 x 239 x 411 x 67 = 13564648105068

Therefore, the lowest common multiple of 521,989,956,822,268 is 13564648105068.

LCM Formula to Find Lowest Common Multiple of 521,989,956,822,268

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 989 x 956 x 822 x 268 = 108517184840544

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

989 : 1, 23, 43, 989

956 : 1, 2, 4, 239, 478, 956

822 : 1, 2, 3, 6, 137, 274, 411, 822

268 : 1, 2, 4, 67, 134, 268

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,989,956,822,268, is 1.

Now, the common factors can be found like this.

521:521

989:23x 43

956:2x 2x 239

822:2x 3x 137

268:2x 2x 67

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 2 = 8

Therefore, the value for common factors is 8.

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 = 108517184840544/(1x8)

LCM = 108517184840544/8

LCM = 13564648105068

Thus, we can understand that the LCM of 521,989,956,822,268 is 13564648105068.
