Given numbers are 628,164,121,629

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

The LCM of 628,164,121,629 is 1959654532.

Find LCM of 628,164,121,629 with Prime Factorization

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

2 x 2 x 157 x 41 x 121 x 629 = 1959654532

Therefore, the lowest common multiple of 628,164,121,629 is 1959654532.

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 164 x 121 x 629 = 7838618128

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

164 : 1, 2, 4, 41, 82, 164

121 : 1, 11, 121

629 : 1, 17, 37, 629

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,164,121,629, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

164:2x 2x 41

121:11x 11

629:17x 37

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 = 7838618128/(1x4)

LCM = 7838618128/4

LCM = 1959654532

Thus, we can understand that the LCM of 628,164,121,629 is 1959654532.
