Given numbers are 628,76,416,621

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

The LCM of 628,76,416,621 is 770616288.

Find LCM of 628,76,416,621 with Prime Factorization

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

2 x 2 x 157 x 19 x 104 x 621 = 770616288

Therefore, the lowest common multiple of 628,76,416,621 is 770616288.

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.

628 x 76 x 416 x 621 = 12329860608

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.

628 : 1, 2, 4, 157, 314, 628

76 : 1, 2, 4, 19, 38, 76

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

621 : 1, 3, 9, 23, 27, 69, 207, 621

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,76,416,621, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

76:2x 2x 19

416:2x 2x 2x 2x 2x 13

621:3x 3x 3x 23

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 2 = 16

Therefore, the value for common factors is 16.

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 = 12329860608/(1x16)

LCM = 12329860608/16

LCM = 770616288

Thus, we can understand that the LCM of 628,76,416,621 is 770616288.
