Calculate the LCM of 717,780,156,823

Given numbers are 717,780,156,823

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

The LCM of 717,780,156,823 is 153423660.

Find LCM of 717,780,156,823 with Prime Factorization


2 717, 780, 156, 823
2 717, 390, 78, 823
3 717, 195, 39, 823
13 239, 65, 13, 823
239, 5, 1, 823

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

2 x 2 x 3 x 13 x 239 x 5 x 1 x 823 = 153423660

Therefore, the lowest common multiple of 717,780,156,823 is 153423660.

LCM Formula to Find Lowest Common Multiple of 717,780,156,823

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.

717 x 780 x 156 x 823 = 71802272880

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.

717 : 1, 3, 239, 717

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

823 : 1, 823

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,780,156,823, is 1.

Now, the common factors can be found like this.

717:3x 239

780:2x 2x 3x 5x 13

156:2x 2x 3x 13

823:823

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 3x 13 = 468

Therefore, the value for common factors is 468.

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 = 71802272880/(1x468)

LCM = 71802272880/468

LCM = 153423660

Thus, we can understand that the LCM of 717,780,156,823 is 153423660.
