Given numbers are 249,516,720,668

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

The LCM of 249,516,720,668 is 429136560.

Find LCM of 249,516,720,668 with Prime Factorization

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

2 x 2 x 3 x 83 x 43 x 60 x 167 = 429136560

Therefore, the lowest common multiple of 249,516,720,668 is 429136560.

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.

249 x 516 x 720 x 668 = 61795664640

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.

249 : 1, 3, 83, 249

516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,516,720,668, is 1.

Now, the common factors can be found like this.

249:3x 83

516:2x 2x 3x 43

720:2x 2x 2x 2x 3x 3x 5

668:2x 2x 167

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 2x 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 61795664640/(1x144)

LCM = 61795664640/144

LCM = 429136560

Thus, we can understand that the LCM of 249,516,720,668 is 429136560.
