Given numbers are 625,627,457,720

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

The LCM of 625,627,457,720 is 8596170000.

Find LCM of 625,627,457,720 with Prime Factorization

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

3 x 5 x 125 x 209 x 457 x 48 = 8596170000

Therefore, the lowest common multiple of 625,627,457,720 is 8596170000.

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 627 x 457 x 720 = 128942550000

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

627 : 1, 3, 11, 19, 33, 57, 209, 627

457 : 1, 457

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 625,627,457,720, is 1.

Now, the common factors can be found like this.

625:5x 5x 5x 5

627:3x 11x 19

457:457

720:2x 2x 2x 2x 3x 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 = 128942550000/(1x15)

LCM = 128942550000/15

LCM = 8596170000

Thus, we can understand that the LCM of 625,627,457,720 is 8596170000.
