Given numbers are 249,530,620,515

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

The LCM of 249,530,620,515 is 842760420.

Find LCM of 249,530,620,515 with Prime Factorization

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

2 x 5 x 249 x 53 x 62 x 103 = 842760420

Therefore, the lowest common multiple of 249,530,620,515 is 842760420.

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 530 x 620 x 515 = 42138021000

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

530 : 1, 2, 5, 10, 53, 106, 265, 530

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

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,530,620,515, is 1.

Now, the common factors can be found like this.

249:3x 83

530:2x 5x 53

620:2x 2x 5x 31

515:5x 103

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

2x 5x 5 = 50

Therefore, the value for common factors is 50.

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 = 42138021000/(1x50)

LCM = 42138021000/50

LCM = 842760420

Thus, we can understand that the LCM of 249,530,620,515 is 842760420.
