Given numbers are 784,539,876,728,671

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

The LCM of 784,539,876,728,671 is 1497704208.

Find LCM of 784,539,876,728,671 with Prime Factorization

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

2 x 2 x 2 x 7 x 7 x 11 x 2 x 1 x 219 x 13 x 61 = 1497704208

Therefore, the lowest common multiple of 784,539,876,728,671 is 1497704208.

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.

784 x 539 x 876 x 728 x 671 = 180826815257088

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.

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

539 : 1, 7, 11, 49, 77, 539

876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876

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

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,539,876,728,671, is 1.

Now, the common factors can be found like this.

784:2x 2x 2x 2x 7x 7

539:7x 7x 11

876:2x 2x 3x 73

728:2x 2x 2x 7x 13

671:11x 61

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 7x 7x 11 = 120736

Therefore, the value for common factors is 120736.

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 = 180826815257088/(1x120736)

LCM = 180826815257088/120736

LCM = 1497704208

Thus, we can understand that the LCM of 784,539,876,728,671 is 1497704208.
