Given numbers are 625,611,198,15

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

The LCM of 625,611,198,15 is 75611250.

Find LCM of 625,611,198,15 with Prime Factorization

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

3 x 5 x 125 x 611 x 66 x 1 = 75611250

Therefore, the lowest common multiple of 625,611,198,15 is 75611250.

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.

625 x 611 x 198 x 15 = 1134168750

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.

625 : 1, 5, 25, 125, 625

611 : 1, 13, 47, 611

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

15 : 1, 3, 5, 15

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 625,611,198,15, is 1.

Now, the common factors can be found like this.

625:5x 5x 5x 5

611:13x 47

198:2x 3x 3x 11

15:3x 5

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 1134168750/(1x15)

LCM = 1134168750/15

LCM = 75611250

Thus, we can understand that the LCM of 625,611,198,15 is 75611250.
