Given numbers are 628,663,218,194

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

The LCM of 628,663,218,194 is 4402216572.

Find LCM of 628,663,218,194 with Prime Factorization

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

2 x 314 x 663 x 109 x 97 = 4402216572

Therefore, the lowest common multiple of 628,663,218,194 is 4402216572.

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 663 x 218 x 194 = 17608866288

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

663 : 1, 3, 13, 17, 39, 51, 221, 663

218 : 1, 2, 109, 218

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,663,218,194, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

663:3x 13x 17

218:2x 109

194:2x 97

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 17608866288/(1x4)

LCM = 17608866288/4

LCM = 4402216572

Thus, we can understand that the LCM of 628,663,218,194 is 4402216572.
