Calculate the LCM of 812,965,688

Given numbers are 812,965,688

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 812,965,688 is 134775760.

Find LCM of 812,965,688 with Prime Factorization


2 812, 965, 688
2 406, 965, 344
203, 965, 172

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

2 x 2 x 203 x 965 x 172 = 134775760

Therefore, the lowest common multiple of 812,965,688 is 134775760.

LCM Formula to Find Lowest Common Multiple of 812,965,688

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 965 x 688 = 539103040

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

965 : 1, 5, 193, 965

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,965,688, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

965:5x 193

688:2x 2x 2x 2x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 539103040/(1x4)

LCM = 539103040/4

LCM = 134775760

Thus, we can understand that the LCM of 812,965,688 is 134775760.
