Find LCM of 708,656,685,928,356 with Prime Factorization


2 708, 656, 685, 928, 356
2 354, 328, 685, 464, 178
2 177, 164, 685, 232, 89
2 177, 82, 685, 116, 89
177, 41, 685, 58, 89

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

2 x 2 x 2 x 2 x 177 x 41 x 685 x 58 x 89 = 410568548640

Therefore, the lowest common multiple of 708,656,685,928,356 is 410568548640.

LCM Formula to Find Lowest Common Multiple of 708,656,685,928,356

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.

708 x 656 x 685 x 928 x 356 = 105105548451840

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.

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

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

685 : 1, 5, 137, 685

928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928

356 : 1, 2, 4, 89, 178, 356

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,656,685,928,356, is 1.

Now, the common factors can be found like this.

708:2x 2x 3x 59

656:2x 2x 2x 2x 41

685:5x 137

928:2x 2x 2x 2x 2x 29

356:2x 2x 89

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 2x 2x 2x 2x 2 = 256

Therefore, the value for common factors is 256.

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 = 105105548451840/(1x256)

LCM = 105105548451840/256

LCM = 410568548640

Thus, we can understand that the LCM of 708,656,685,928,356 is 410568548640.
