Find LCM of 856,792,776,390 with Prime Factorization


2 856, 792, 776, 390
2 428, 396, 388, 195
2 214, 198, 194, 195
3 107, 99, 97, 195
107, 33, 97, 65

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

2 x 2 x 2 x 3 x 107 x 33 x 97 x 65 = 534310920

Therefore, the lowest common multiple of 856,792,776,390 is 534310920.

LCM Formula to Find Lowest Common Multiple of 856,792,776,390

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.

856 x 792 x 776 x 390 = 205175393280

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.

856 : 1, 2, 4, 8, 107, 214, 428, 856

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

776 : 1, 2, 4, 8, 97, 194, 388, 776

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,792,776,390, is 2.

Now, the common factors can be found like this.

856:2x 2x 2x 107

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

776:2x 2x 2x 97

390:2x 3x 5x 13

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 = 205175393280/(2x192)

LCM = 205175393280/384

LCM = 534310920

Thus, we can understand that the LCM of 856,792,776,390 is 534310920.
