Given numbers are 577,398,221,636

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

The LCM of 577,398,221,636 is 16139061588.

Find LCM of 577,398,221,636 with Prime Factorization

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

2 x 577 x 199 x 221 x 318 = 16139061588

Therefore, the lowest common multiple of 577,398,221,636 is 16139061588.

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.

577 x 398 x 221 x 636 = 32278123176

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.

577 : 1, 577

398 : 1, 2, 199, 398

221 : 1, 13, 17, 221

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 577,398,221,636, is 1.

Now, the common factors can be found like this.

577:577

398:2x 199

221:13x 17

636:2x 2x 3x 53

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

2 = 2

Therefore, the value for common factors is 2.

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 = 32278123176/(1x2)

LCM = 32278123176/2

LCM = 16139061588

Thus, we can understand that the LCM of 577,398,221,636 is 16139061588.
