Given numbers are 435,642,772,388

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

The LCM of 435,642,772,388 is 3485475780.

Find LCM of 435,642,772,388 with Prime Factorization

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

2 x 2 x 3 x 145 x 107 x 193 x 97 = 3485475780

Therefore, the lowest common multiple of 435,642,772,388 is 3485475780.

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.

435 x 642 x 772 x 388 = 83651418720

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.

435 : 1, 3, 5, 15, 29, 87, 145, 435

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

772 : 1, 2, 4, 193, 386, 772

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 435,642,772,388, is 1.

Now, the common factors can be found like this.

435:3x 5x 29

642:2x 3x 107

772:2x 2x 193

388:2x 2x 97

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 3 = 24

Therefore, the value for common factors is 24.

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 = 83651418720/(1x24)

LCM = 83651418720/24

LCM = 3485475780

Thus, we can understand that the LCM of 435,642,772,388 is 3485475780.
