Find LCM of 786,858,407,851 with Prime Factorization


2 786, 858, 407, 851
3 393, 429, 407, 851
11 131, 143, 407, 851
37 131, 13, 37, 851
131, 13, 1, 23

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

2 x 3 x 11 x 37 x 131 x 13 x 1 x 23 = 95650698

Therefore, the lowest common multiple of 786,858,407,851 is 95650698.

LCM Formula to Find Lowest Common Multiple of 786,858,407,851

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.

786 x 858 x 407 x 851 = 233579004516

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

407 : 1, 11, 37, 407

851 : 1, 23, 37, 851

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,858,407,851, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

858:2x 3x 11x 13

407:11x 37

851:23x 37

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 11x 37 = 2442

Therefore, the value for common factors is 2442.

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 = 233579004516/(1x2442)

LCM = 233579004516/2442

LCM = 95650698

Thus, we can understand that the LCM of 786,858,407,851 is 95650698.
