Calculate the LCM of 678,306,123,808

Given numbers are 678,306,123,808

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

The LCM of 678,306,123,808 is 572749992.

Find LCM of 678,306,123,808 with Prime Factorization


2 678, 306, 123, 808
3 339, 153, 123, 404
113, 51, 41, 404

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

2 x 3 x 113 x 51 x 41 x 404 = 572749992

Therefore, the lowest common multiple of 678,306,123,808 is 572749992.

LCM Formula to Find Lowest Common Multiple of 678,306,123,808

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.

678 x 306 x 123 x 808 = 20618999712

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

123 : 1, 3, 41, 123

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,306,123,808, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

306:2x 3x 3x 17

123:3x 41

808:2x 2x 2x 101

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 20618999712/(1x36)

LCM = 20618999712/36

LCM = 572749992

Thus, we can understand that the LCM of 678,306,123,808 is 572749992.
