The LCM of 634,528,878,305,920 is 515448618960.

Find LCM of 634,528,878,305,920 with Prime Factorization


2 634, 528, 878, 305, 920
2 317, 264, 439, 305, 460
2 317, 132, 439, 305, 230
5 317, 66, 439, 305, 115
317, 66, 439, 61, 23

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

2 x 2 x 2 x 5 x 317 x 66 x 439 x 61 x 23 = 515448618960

Therefore, the lowest common multiple of 634,528,878,305,920 is 515448618960.

LCM Formula to Find Lowest Common Multiple of 634,528,878,305,920

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.

634 x 528 x 878 x 305 x 920 = 82471779033600

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.

634 : 1, 2, 317, 634

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

878 : 1, 2, 439, 878

305 : 1, 5, 61, 305

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,528,878,305,920, is 1.

Now, the common factors can be found like this.

634:2x 317

528:2x 2x 2x 2x 3x 11

878:2x 439

305:5x 61

920:2x 2x 2x 5x 23

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 5 = 160

Therefore, the value for common factors is 160.

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 = 82471779033600/(1x160)

LCM = 82471779033600/160

LCM = 515448618960

Thus, we can understand that the LCM of 634,528,878,305,920 is 515448618960.
