Calculate the LCM of 793,771,230,780

Given numbers are 793,771,230,780

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

The LCM of 793,771,230,780 is 281245380.

Find LCM of 793,771,230,780 with Prime Factorization


2 793, 771, 230, 780
3 793, 771, 115, 390
5 793, 257, 115, 130
13 793, 257, 23, 26
61, 257, 23, 2

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

2 x 3 x 5 x 13 x 61 x 257 x 23 x 2 = 281245380

Therefore, the lowest common multiple of 793,771,230,780 is 281245380.

LCM Formula to Find Lowest Common Multiple of 793,771,230,780

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.

793 x 771 x 230 x 780 = 109685698200

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.

793 : 1, 13, 61, 793

771 : 1, 3, 257, 771

230 : 1, 2, 5, 10, 23, 46, 115, 230

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,771,230,780, is 1.

Now, the common factors can be found like this.

793:13x 61

771:3x 257

230:2x 5x 23

780:2x 2x 3x 5x 13

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 = 109685698200/(1x390)

LCM = 109685698200/390

LCM = 281245380

Thus, we can understand that the LCM of 793,771,230,780 is 281245380.
