Given numbers are 639,402,698,191

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

The LCM of 639,402,698,191 is 5707743534.

Find LCM of 639,402,698,191 with Prime Factorization

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

2 x 3 x 213 x 67 x 349 x 191 = 5707743534

Therefore, the lowest common multiple of 639,402,698,191 is 5707743534.

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 402 x 698 x 191 = 34246461204

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

402 : 1, 2, 3, 6, 67, 134, 201, 402

698 : 1, 2, 349, 698

191 : 1, 191

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,402,698,191, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

402:2x 3x 67

698:2x 349

191:191

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 = 34246461204/(1x6)

LCM = 34246461204/6

LCM = 5707743534

Thus, we can understand that the LCM of 639,402,698,191 is 5707743534.
