Given numbers are 668,209,956,123

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

The LCM of 668,209,956,123 is 4104173964.

Find LCM of 668,209,956,123 with Prime Factorization

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

2 x 2 x 167 x 209 x 239 x 123 = 4104173964

Therefore, the lowest common multiple of 668,209,956,123 is 4104173964.

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.

668 x 209 x 956 x 123 = 16416695856

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.

668 : 1, 2, 4, 167, 334, 668

209 : 1, 11, 19, 209

956 : 1, 2, 4, 239, 478, 956

123 : 1, 3, 41, 123

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,209,956,123, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

209:11x 19

956:2x 2x 239

123:3x 41

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 = 16416695856/(1x4)

LCM = 16416695856/4

LCM = 4104173964

Thus, we can understand that the LCM of 668,209,956,123 is 4104173964.
