Calculate the LCM of 656,391,495,626,209

Given numbers are 656,391,495,626,209

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

The LCM of 656,391,495,626,209 is 755063947440.

Find LCM of 656,391,495,626,209 with Prime Factorization


2 656, 391, 495, 626, 209
11 328, 391, 495, 313, 209
328, 391, 45, 313, 19

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

2 x 11 x 328 x 391 x 45 x 313 x 19 = 755063947440

Therefore, the lowest common multiple of 656,391,495,626,209 is 755063947440.

LCM Formula to Find Lowest Common Multiple of 656,391,495,626,209

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.

656 x 391 x 495 x 626 x 209 = 16611406843680

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.

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

391 : 1, 17, 23, 391

495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495

626 : 1, 2, 313, 626

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 656,391,495,626,209, is 1.

Now, the common factors can be found like this.

656:2x 2x 2x 2x 41

391:17x 23

495:3x 3x 5x 11

626:2x 313

209:11x 19

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 16611406843680/(1x22)

LCM = 16611406843680/22

LCM = 755063947440

Thus, we can understand that the LCM of 656,391,495,626,209 is 755063947440.
