Given numbers are 641,728,336,476

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

The LCM of 641,728,336,476 is 47598096.

Find LCM of 641,728,336,476 with Prime Factorization

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

2 x 2 x 2 x 7 x 641 x 13 x 6 x 17 = 47598096

Therefore, the lowest common multiple of 641,728,336,476 is 47598096.

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 728 x 336 x 476 = 74633814528

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,728,336,476, is 1.

Now, the common factors can be found like this.

641:641

728:2x 2x 2x 7x 13

336:2x 2x 2x 2x 3x 7

476:2x 2x 7x 17

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 7x 7 = 1568

Therefore, the value for common factors is 1568.

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 = 74633814528/(1x1568)

LCM = 74633814528/1568

LCM = 47598096

Thus, we can understand that the LCM of 641,728,336,476 is 47598096.
