Calculate the LCM of 791,768,391,387

Given numbers are 791,768,391,387

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

The LCM of 791,768,391,387 is 30641087232.

Find LCM of 791,768,391,387 with Prime Factorization


3 791, 768, 391, 387
791, 256, 391, 129

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

3 x 791 x 256 x 391 x 129 = 30641087232

Therefore, the lowest common multiple of 791,768,391,387 is 30641087232.

LCM Formula to Find Lowest Common Multiple of 791,768,391,387

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 768 x 391 x 387 = 91923261696

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

768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768

391 : 1, 17, 23, 391

387 : 1, 3, 9, 43, 129, 387

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,768,391,387, is 1.

Now, the common factors can be found like this.

791:7x 113

768:2x 2x 2x 2x 2x 2x 2x 2x 3

391:17x 23

387:3x 3x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3 = 3

Therefore, the value for common factors is 3.

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 = 91923261696/(1x3)

LCM = 91923261696/3

LCM = 30641087232

Thus, we can understand that the LCM of 791,768,391,387 is 30641087232.
