Find LCM of 328,640,928,731 with Prime Factorization


2 328, 640, 928, 731
2 164, 320, 464, 731
2 82, 160, 232, 731
2 41, 80, 116, 731
2 41, 40, 58, 731
41, 20, 29, 731

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

2 x 2 x 2 x 2 x 2 x 41 x 20 x 29 x 731 = 556261760

Therefore, the lowest common multiple of 328,640,928,731 is 556261760.

LCM Formula to Find Lowest Common Multiple of 328,640,928,731

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.

328 x 640 x 928 x 731 = 142403010560

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.

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

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

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

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,640,928,731, is 1.

Now, the common factors can be found like this.

328:2x 2x 2x 41

640:2x 2x 2x 2x 2x 2x 2x 5

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

731:17x 43

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 = 142403010560/(1x256)

LCM = 142403010560/256

LCM = 556261760

Thus, we can understand that the LCM of 328,640,928,731 is 556261760.
