Given numbers are 643,646,337,988,950

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

The LCM of 643,646,337,988,950 is 90988550900.

Find LCM of 643,646,337,988,950 with Prime Factorization

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

2 x 19 x 643 x 17 x 337 x 26 x 25 = 90988550900

Therefore, the lowest common multiple of 643,646,337,988,950 is 90988550900.

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.

643 x 646 x 337 x 988 x 950 = 131387467499600

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.

643 : 1, 643

646 : 1, 2, 17, 19, 34, 38, 323, 646

337 : 1, 337

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,646,337,988,950, is 1.

Now, the common factors can be found like this.

643:643

646:2x 17x 19

337:337

988:2x 2x 13x 19

950:2x 5x 5x 19

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

2x 2x 19x 19 = 1444

Therefore, the value for common factors is 1444.

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 = 131387467499600/(1x1444)

LCM = 131387467499600/1444

LCM = 90988550900

Thus, we can understand that the LCM of 643,646,337,988,950 is 90988550900.
