Given numbers are 668,869,133,209

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

The LCM of 668,869,133,209 is 77205436.

Find LCM of 668,869,133,209 with Prime Factorization

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

11 x 19 x 668 x 79 x 7 x 1 = 77205436

Therefore, the lowest common multiple of 668,869,133,209 is 77205436.

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 869 x 133 x 209 = 16135936124

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

869 : 1, 11, 79, 869

133 : 1, 7, 19, 133

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,869,133,209, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

869:11x 79

133:7x 19

209:11x 19

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

11x 19 = 209

Therefore, the value for common factors is 209.

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 = 16135936124/(1x209)

LCM = 16135936124/209

LCM = 77205436

Thus, we can understand that the LCM of 668,869,133,209 is 77205436.
