Calculate the LCM of 787,117,676,894

Given numbers are 787,117,676,894

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

The LCM of 787,117,676,894 is 713428092.

Find LCM of 787,117,676,894 with Prime Factorization


2 787, 117, 676, 894
3 787, 117, 338, 447
13 787, 39, 338, 149
787, 3, 26, 149

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

2 x 3 x 13 x 787 x 3 x 26 x 149 = 713428092

Therefore, the lowest common multiple of 787,117,676,894 is 713428092.

LCM Formula to Find Lowest Common Multiple of 787,117,676,894

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.

787 x 117 x 676 x 894 = 55647391176

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.

787 : 1, 787

117 : 1, 3, 9, 13, 39, 117

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

894 : 1, 2, 3, 6, 149, 298, 447, 894

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,117,676,894, is 1.

Now, the common factors can be found like this.

787:787

117:3x 3x 13

676:2x 2x 13x 13

894:2x 3x 149

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 13 = 78

Therefore, the value for common factors is 78.

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 = 55647391176/(1x78)

LCM = 55647391176/78

LCM = 713428092

Thus, we can understand that the LCM of 787,117,676,894 is 713428092.
