Given numbers are 628,214,165,671

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

The LCM of 628,214,165,671 is 676327740.

Find LCM of 628,214,165,671 with Prime Factorization

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

2 x 11 x 314 x 107 x 15 x 61 = 676327740

Therefore, the lowest common multiple of 628,214,165,671 is 676327740.

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 214 x 165 x 671 = 14879210280

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

214 : 1, 2, 107, 214

165 : 1, 3, 5, 11, 15, 33, 55, 165

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,214,165,671, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

214:2x 107

165:3x 5x 11

671:11x 61

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 14879210280/(1x22)

LCM = 14879210280/22

LCM = 676327740

Thus, we can understand that the LCM of 628,214,165,671 is 676327740.
