Given numbers are 639,175,681,956,402

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

The LCM of 639,175,681,956,402 is 1625913582300.

Find LCM of 639,175,681,956,402 with Prime Factorization

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

2 x 3 x 213 x 175 x 227 x 478 x 67 = 1625913582300

Therefore, the lowest common multiple of 639,175,681,956,402 is 1625913582300.

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 175 x 681 x 956 x 402 = 29266444481400

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

175 : 1, 5, 7, 25, 35, 175

681 : 1, 3, 227, 681

956 : 1, 2, 4, 239, 478, 956

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,175,681,956,402, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

175:5x 5x 7

681:3x 227

956:2x 2x 239

402:2x 3x 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 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 29266444481400/(1x18)

LCM = 29266444481400/18

LCM = 1625913582300

Thus, we can understand that the LCM of 639,175,681,956,402 is 1625913582300.
