Calculate the LCM of 791,852,390,660

Given numbers are 791,852,390,660

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

The LCM of 791,852,390,660 is 481861380.

Find LCM of 791,852,390,660 with Prime Factorization


2 791, 852, 390, 660
2 791, 426, 195, 330
3 791, 213, 195, 165
5 791, 71, 65, 55
791, 71, 13, 11

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

2 x 2 x 3 x 5 x 791 x 71 x 13 x 11 = 481861380

Therefore, the lowest common multiple of 791,852,390,660 is 481861380.

LCM Formula to Find Lowest Common Multiple of 791,852,390,660

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.

791 x 852 x 390 x 660 = 173470096800

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.

791 : 1, 7, 113, 791

852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852

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

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,852,390,660, is 1.

Now, the common factors can be found like this.

791:7x 113

852:2x 2x 3x 71

390:2x 3x 5x 13

660:2x 2x 3x 5x 11

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 2x 3x 3x 5 = 360

Therefore, the value for common factors is 360.

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 = 173470096800/(1x360)

LCM = 173470096800/360

LCM = 481861380

Thus, we can understand that the LCM of 791,852,390,660 is 481861380.
