Calculate the LCM of 698,405,704,591

Given numbers are 698,405,704,591

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

The LCM of 698,405,704,591 is 19602855360.

Find LCM of 698,405,704,591 with Prime Factorization


2 698, 405, 704, 591
3 349, 405, 352, 591
349, 135, 352, 197

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

2 x 3 x 349 x 135 x 352 x 197 = 19602855360

Therefore, the lowest common multiple of 698,405,704,591 is 19602855360.

LCM Formula to Find Lowest Common Multiple of 698,405,704,591

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.

698 x 405 x 704 x 591 = 117617132160

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.

698 : 1, 2, 349, 698

405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

591 : 1, 3, 197, 591

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,405,704,591, is 1.

Now, the common factors can be found like this.

698:2x 349

405:3x 3x 3x 3x 5

704:2x 2x 2x 2x 2x 2x 11

591:3x 197

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 117617132160/(1x6)

LCM = 117617132160/6

LCM = 19602855360

Thus, we can understand that the LCM of 698,405,704,591 is 19602855360.
