Given numbers are 454,996,476,721,728

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

The LCM of 454,996,476,721,728 is 72051450744.

Find LCM of 454,996,476,721,728 with Prime Factorization

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

2 x 2 x 7 x 227 x 249 x 17 x 103 x 26 = 72051450744

Therefore, the lowest common multiple of 454,996,476,721,728 is 72051450744.

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.

454 x 996 x 476 x 721 x 728 = 112976674766592

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.

454 : 1, 2, 227, 454

996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996

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

721 : 1, 7, 103, 721

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 454,996,476,721,728, is 1.

Now, the common factors can be found like this.

454:2x 227

996:2x 2x 3x 83

476:2x 2x 7x 17

721:7x 103

728:2x 2x 2x 7x 13

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 = 112976674766592/(1x1568)

LCM = 112976674766592/1568

LCM = 72051450744

Thus, we can understand that the LCM of 454,996,476,721,728 is 72051450744.
