Calculate the LCM of 793,290,462,390

Given numbers are 793,290,462,390

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

The LCM of 793,290,462,390 is 53123070.

Find LCM of 793,290,462,390 with Prime Factorization


2 793, 290, 462, 390
3 793, 145, 231, 195
5 793, 145, 77, 65
13 793, 29, 77, 13
61, 29, 77, 1

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

2 x 3 x 5 x 13 x 61 x 29 x 77 x 1 = 53123070

Therefore, the lowest common multiple of 793,290,462,390 is 53123070.

LCM Formula to Find Lowest Common Multiple of 793,290,462,390

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 290 x 462 x 390 = 41435994600

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

290 : 1, 2, 5, 10, 29, 58, 145, 290

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,290,462,390, is 1.

Now, the common factors can be found like this.

793:13x 61

290:2x 5x 29

462:2x 3x 7x 11

390:2x 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 2x 3x 5x 13 = 780

Therefore, the value for common factors is 780.

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 = 41435994600/(1x780)

LCM = 41435994600/780

LCM = 53123070

Thus, we can understand that the LCM of 793,290,462,390 is 53123070.
