Find LCM of 497,821,280,512,684 with Prime Factorization


2 497, 821, 280, 512, 684
2 497, 821, 140, 256, 342
2 497, 821, 70, 128, 171
7 497, 821, 35, 64, 171
71, 821, 5, 64, 171

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

2 x 2 x 2 x 7 x 71 x 821 x 5 x 64 x 171 = 178622277120

Therefore, the lowest common multiple of 497,821,280,512,684 is 178622277120.

LCM Formula to Find Lowest Common Multiple of 497,821,280,512,684

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.

497 x 821 x 280 x 512 x 684 = 40011390074880

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.

497 : 1, 7, 71, 497

821 : 1, 821

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,821,280,512,684, is 1.

Now, the common factors can be found like this.

497:7x 71

821:821

280:2x 2x 2x 5x 7

512:2x 2x 2x 2x 2x 2x 2x 2x 2

684:2x 2x 3x 3x 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 2x 2x 2x 2x 7 = 224

Therefore, the value for common factors is 224.

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 = 40011390074880/(1x224)

LCM = 40011390074880/224

LCM = 178622277120

Thus, we can understand that the LCM of 497,821,280,512,684 is 178622277120.
