Calculate the LCM of 663,620,558

Given numbers are 663,620,558

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

The LCM of 663,620,558 is 1233180.

Find LCM of 663,620,558 with Prime Factorization


2 663, 620, 558
3 663, 310, 279
31 221, 310, 93
221, 10, 3

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

2 x 3 x 31 x 221 x 10 x 3 = 1233180

Therefore, the lowest common multiple of 663,620,558 is 1233180.

LCM Formula to Find Lowest Common Multiple of 663,620,558

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.

663 x 620 x 558 = 229371480

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.

663 : 1, 3, 13, 17, 39, 51, 221, 663

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,620,558, is 1.

Now, the common factors can be found like this.

663:3x 13x 17

620:2x 2x 5x 31

558:2x 3x 3x 31

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

2x 3x 31 = 186

Therefore, the value for common factors is 186.

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 = 229371480/(1x186)

LCM = 229371480/186

LCM = 1233180

Thus, we can understand that the LCM of 663,620,558 is 1233180.
