Given numbers are 791,398,771,440

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

The LCM of 791,398,771,440 is 53399429160.

Find LCM of 791,398,771,440 with Prime Factorization

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

2 x 791 x 199 x 771 x 220 = 53399429160

Therefore, the lowest common multiple of 791,398,771,440 is 53399429160.

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 398 x 771 x 440 = 106798858320

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

398 : 1, 2, 199, 398

771 : 1, 3, 257, 771

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,398,771,440, is 1.

Now, the common factors can be found like this.

791:7x 113

398:2x 199

771:3x 257

440:2x 2x 2x 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.

2 = 2

Therefore, the value for common factors is 2.

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 = 106798858320/(1x2)

LCM = 106798858320/2

LCM = 53399429160

Thus, we can understand that the LCM of 791,398,771,440 is 53399429160.
