Given numbers are 639,542,683,668,269

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

The LCM of 639,542,683,668,269 is 21252968336484.

Find LCM of 639,542,683,668,269 with Prime Factorization

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

2 x 639 x 271 x 683 x 334 x 269 = 21252968336484

Therefore, the lowest common multiple of 639,542,683,668,269 is 21252968336484.

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.

639 x 542 x 683 x 668 x 269 = 42505936672968

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.

639 : 1, 3, 9, 71, 213, 639

542 : 1, 2, 271, 542

683 : 1, 683

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

269 : 1, 269

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,542,683,668,269, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

542:2x 271

683:683

668:2x 2x 167

269:269

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

2 = 2

Therefore, the value for common factors is 2.

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 = 42505936672968/(1x2)

LCM = 42505936672968/2

LCM = 21252968336484

Thus, we can understand that the LCM of 639,542,683,668,269 is 21252968336484.
