Find LCM of 428,792,843,940,284 with Prime Factorization


2 428, 792, 843, 940, 284
2 214, 396, 843, 470, 142
3 107, 198, 843, 235, 71
107, 66, 281, 235, 71

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

2 x 2 x 3 x 107 x 66 x 281 x 235 x 71 = 397320972840

Therefore, the lowest common multiple of 428,792,843,940,284 is 397320972840.

LCM Formula to Find Lowest Common Multiple of 428,792,843,940,284

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.

428 x 792 x 843 x 940 x 284 = 76285626785280

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.

428 : 1, 2, 4, 107, 214, 428

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

843 : 1, 3, 281, 843

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,792,843,940,284, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

792:2x 2x 2x 3x 3x 11

843:3x 281

940:2x 2x 5x 47

284:2x 2x 71

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 3 = 192

Therefore, the value for common factors is 192.

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 = 76285626785280/(1x192)

LCM = 76285626785280/192

LCM = 397320972840

Thus, we can understand that the LCM of 428,792,843,940,284 is 397320972840.
