The LCM of 771,394,873,675,642 is 709395827850.

Find LCM of 771,394,873,675,642 with Prime Factorization


2 771, 394, 873, 675, 642
3 771, 197, 873, 675, 321
3 257, 197, 291, 225, 107
257, 197, 97, 75, 107

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

2 x 3 x 3 x 257 x 197 x 97 x 75 x 107 = 709395827850

Therefore, the lowest common multiple of 771,394,873,675,642 is 709395827850.

LCM Formula to Find Lowest Common Multiple of 771,394,873,675,642

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.

771 x 394 x 873 x 675 x 642 = 114922124111700

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.

771 : 1, 3, 257, 771

394 : 1, 2, 197, 394

873 : 1, 3, 9, 97, 291, 873

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,394,873,675,642, is 1.

Now, the common factors can be found like this.

771:3x 257

394:2x 197

873:3x 3x 97

675:3x 3x 3x 5x 5

642:2x 3x 107

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 3x 3x 3 = 162

Therefore, the value for common factors is 162.

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 = 114922124111700/(1x162)

LCM = 114922124111700/162

LCM = 709395827850

Thus, we can understand that the LCM of 771,394,873,675,642 is 709395827850.
