Given numbers are 782,690,646,452,873

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

The LCM of 782,690,646,452,873 is 14657268420.

Find LCM of 782,690,646,452,873 with Prime Factorization

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

2 x 3 x 17 x 23 x 1 x 5 x 19 x 226 x 291 = 14657268420

Therefore, the lowest common multiple of 782,690,646,452,873 is 14657268420.

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.

782 x 690 x 646 x 452 x 873 = 137543806853280

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.

782 : 1, 2, 17, 23, 34, 46, 391, 782

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

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

452 : 1, 2, 4, 113, 226, 452

873 : 1, 3, 9, 97, 291, 873

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,690,646,452,873, is 1.

Now, the common factors can be found like this.

782:2x 17x 23

690:2x 3x 5x 23

646:2x 17x 19

452:2x 2x 113

873:3x 3x 97

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 3x 17x 23 = 9384

Therefore, the value for common factors is 9384.

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 = 137543806853280/(1x9384)

LCM = 137543806853280/9384

LCM = 14657268420

Thus, we can understand that the LCM of 782,690,646,452,873 is 14657268420.
