Given numbers are 669,164,664,678

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

The LCM of 669,164,664,678 is 2058052728.

Find LCM of 669,164,664,678 with Prime Factorization

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

2 x 2 x 3 x 223 x 41 x 166 x 113 = 2058052728

Therefore, the lowest common multiple of 669,164,664,678 is 2058052728.

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.

669 x 164 x 664 x 678 = 49393265472

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.

669 : 1, 3, 223, 669

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

664 : 1, 2, 4, 8, 83, 166, 332, 664

678 : 1, 2, 3, 6, 113, 226, 339, 678

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,164,664,678, is 1.

Now, the common factors can be found like this.

669:3x 223

164:2x 2x 41

664:2x 2x 2x 83

678:2x 3x 113

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 3 = 24

Therefore, the value for common factors is 24.

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 = 49393265472/(1x24)

LCM = 49393265472/24

LCM = 2058052728

Thus, we can understand that the LCM of 669,164,664,678 is 2058052728.
