Given numbers are 724,616,163,285

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

The LCM of 724,616,163,285 is 5179546680.

Find LCM of 724,616,163,285 with Prime Factorization

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

2 x 2 x 181 x 154 x 163 x 285 = 5179546680

Therefore, the lowest common multiple of 724,616,163,285 is 5179546680.

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.

724 x 616 x 163 x 285 = 20718186720

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.

724 : 1, 2, 4, 181, 362, 724

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

163 : 1, 163

285 : 1, 3, 5, 15, 19, 57, 95, 285

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,616,163,285, is 1.

Now, the common factors can be found like this.

724:2x 2x 181

616:2x 2x 2x 7x 11

163:163

285:3x 5x 19

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 20718186720/(1x4)

LCM = 20718186720/4

LCM = 5179546680

Thus, we can understand that the LCM of 724,616,163,285 is 5179546680.

Here are some samples of LCM of two or more Numbers calculations.
