Given numbers are 639,428,346,938

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

The LCM of 639,428,346,938 is 22190320404.

Find LCM of 639,428,346,938 with Prime Factorization

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

2 x 639 x 214 x 173 x 469 = 22190320404

Therefore, the lowest common multiple of 639,428,346,938 is 22190320404.

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 428 x 346 x 938 = 88761281616

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

428 : 1, 2, 4, 107, 214, 428

346 : 1, 2, 173, 346

938 : 1, 2, 7, 14, 67, 134, 469, 938

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,428,346,938, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

428:2x 2x 107

346:2x 173

938:2x 7x 67

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 = 88761281616/(1x4)

LCM = 88761281616/4

LCM = 22190320404

Thus, we can understand that the LCM of 639,428,346,938 is 22190320404.
