Given numbers are 407,647,647,842

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

The LCM of 407,647,647,842 is 221723018.

Find LCM of 407,647,647,842 with Prime Factorization

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

647 x 407 x 1 x 1 x 842 = 221723018

Therefore, the lowest common multiple of 407,647,647,842 is 221723018.

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.

407 x 647 x 647 x 842 = 143454792646

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.

407 : 1, 11, 37, 407

647 : 1, 647

647 : 1, 647

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,647,647,842, is 1.

Now, the common factors can be found like this.

407:11x 37

647:647

647:647

842:2x 421

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

647 = 647

Therefore, the value for common factors is 647.

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 = 143454792646/(1x647)

LCM = 143454792646/647

LCM = 221723018

Thus, we can understand that the LCM of 407,647,647,842 is 221723018.
