The LCM of 812,957,789,666 is 782255628.

Find LCM of 812,957,789,666 with Prime Factorization


2 812, 957, 789, 666
3 406, 957, 789, 333
29 406, 319, 263, 111
14, 11, 263, 111

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

2 x 3 x 29 x 14 x 11 x 263 x 111 = 782255628

Therefore, the lowest common multiple of 812,957,789,666 is 782255628.

LCM Formula to Find Lowest Common Multiple of 812,957,789,666

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.

812 x 957 x 789 x 666 = 408337437816

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.

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

957 : 1, 3, 11, 29, 33, 87, 319, 957

789 : 1, 3, 263, 789

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,957,789,666, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

957:3x 11x 29

789:3x 263

666:2x 3x 3x 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 3x 29 = 522

Therefore, the value for common factors is 522.

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 = 408337437816/(1x522)

LCM = 408337437816/522

LCM = 782255628

Thus, we can understand that the LCM of 812,957,789,666 is 782255628.
