Given numbers are 641,646,476,612,284

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

The LCM of 641,646,476,612,284 is 3704413356.

Find LCM of 641,646,476,612,284 with Prime Factorization

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

2 x 2 x 17 x 641 x 19 x 7 x 9 x 71 = 3704413356

Therefore, the lowest common multiple of 641,646,476,612,284 is 3704413356.

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.

641 x 646 x 476 x 612 x 284 = 34258414716288

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.

641 : 1, 641

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

476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,646,476,612,284, is 1.

Now, the common factors can be found like this.

641:641

646:2x 17x 19

476:2x 2x 7x 17

612:2x 2x 3x 3x 17

284:2x 2x 71

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 2x 2x 2x 17x 17 = 9248

Therefore, the value for common factors is 9248.

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 = 34258414716288/(1x9248)

LCM = 34258414716288/9248

LCM = 3704413356

Thus, we can understand that the LCM of 641,646,476,612,284 is 3704413356.
