Calculate the LCM of 521,648,536,687

Given numbers are 521,648,536,687

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

The LCM of 521,648,536,687 is 5179919544.

Find LCM of 521,648,536,687 with Prime Factorization


2 521, 648, 536, 687
2 521, 324, 268, 687
2 521, 162, 134, 687
3 521, 81, 67, 687
521, 27, 67, 229

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

2 x 2 x 2 x 3 x 521 x 27 x 67 x 229 = 5179919544

Therefore, the lowest common multiple of 521,648,536,687 is 5179919544.

LCM Formula to Find Lowest Common Multiple of 521,648,536,687

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 648 x 536 x 687 = 124318069056

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

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

536 : 1, 2, 4, 8, 67, 134, 268, 536

687 : 1, 3, 229, 687

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,648,536,687, is 1.

Now, the common factors can be found like this.

521:521

648:2x 2x 2x 3x 3x 3x 3

536:2x 2x 2x 67

687:3x 229

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 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 124318069056/(1x24)

LCM = 124318069056/24

LCM = 5179919544

Thus, we can understand that the LCM of 521,648,536,687 is 5179919544.
