Given numbers are 780,161,634,327,642

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

The LCM of 780,161,634,327,642 is 464290734180.

Find LCM of 780,161,634,327,642 with Prime Factorization

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

2 x 3 x 130 x 161 x 317 x 109 x 107 = 464290734180

Therefore, the lowest common multiple of 780,161,634,327,642 is 464290734180.

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.

780 x 161 x 634 x 327 x 642 = 16714466430480

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

161 : 1, 7, 23, 161

634 : 1, 2, 317, 634

327 : 1, 3, 109, 327

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 780,161,634,327,642, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

161:7x 23

634:2x 317

327:3x 109

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 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 16714466430480/(1x36)

LCM = 16714466430480/36

LCM = 464290734180

Thus, we can understand that the LCM of 780,161,634,327,642 is 464290734180.
