Calculate the LCM of 489,715,780,158

Given numbers are 489,715,780,158

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

The LCM of 489,715,780,158 is 110484660.

Find LCM of 489,715,780,158 with Prime Factorization


2 489, 715, 780, 158
3 489, 715, 390, 79
5 163, 715, 130, 79
13 163, 143, 26, 79
163, 11, 2, 79

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

2 x 3 x 5 x 13 x 163 x 11 x 2 x 79 = 110484660

Therefore, the lowest common multiple of 489,715,780,158 is 110484660.

LCM Formula to Find Lowest Common Multiple of 489,715,780,158

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.

489 x 715 x 780 x 158 = 43089017400

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.

489 : 1, 3, 163, 489

715 : 1, 5, 11, 13, 55, 65, 143, 715

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

158 : 1, 2, 79, 158

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,715,780,158, is 1.

Now, the common factors can be found like this.

489:3x 163

715:5x 11x 13

780:2x 2x 3x 5x 13

158:2x 79

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 5x 13 = 390

Therefore, the value for common factors is 390.

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 = 43089017400/(1x390)

LCM = 43089017400/390

LCM = 110484660

Thus, we can understand that the LCM of 489,715,780,158 is 110484660.
