Calculate the LCM of 660,371,491,261,604

Given numbers are 660,371,491,261,604

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

The LCM of 660,371,491,261,604 is 1579412377620.

Find LCM of 660,371,491,261,604 with Prime Factorization


2 660, 371, 491, 261, 604
2 330, 371, 491, 261, 302
3 165, 371, 491, 261, 151
55, 371, 491, 87, 151

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

2 x 2 x 3 x 55 x 371 x 491 x 87 x 151 = 1579412377620

Therefore, the lowest common multiple of 660,371,491,261,604 is 1579412377620.

LCM Formula to Find Lowest Common Multiple of 660,371,491,261,604

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.

660 x 371 x 491 x 261 x 604 = 18952948531440

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.

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

371 : 1, 7, 53, 371

491 : 1, 491

261 : 1, 3, 9, 29, 87, 261

604 : 1, 2, 4, 151, 302, 604

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,371,491,261,604, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

371:7x 53

491:491

261:3x 3x 29

604:2x 2x 151

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 = 18952948531440/(1x12)

LCM = 18952948531440/12

LCM = 1579412377620

Thus, we can understand that the LCM of 660,371,491,261,604 is 1579412377620.
