Given numbers are 639,822,209,292

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

The LCM of 639,822,209,292 is 5342574204.

Find LCM of 639,822,209,292 with Prime Factorization

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

2 x 3 x 213 x 137 x 209 x 146 = 5342574204

Therefore, the lowest common multiple of 639,822,209,292 is 5342574204.

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 822 x 209 x 292 = 32055445224

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

822 : 1, 2, 3, 6, 137, 274, 411, 822

209 : 1, 11, 19, 209

292 : 1, 2, 4, 73, 146, 292

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,822,209,292, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

822:2x 3x 137

209:11x 19

292:2x 2x 73

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 32055445224/(1x6)

LCM = 32055445224/6

LCM = 5342574204

Thus, we can understand that the LCM of 639,822,209,292 is 5342574204.
