Given numbers are 646,403,796,924,921

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

The LCM of 646,403,796,924,921 is 7348031198508.

Find LCM of 646,403,796,924,921 with Prime Factorization

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

2 x 2 x 3 x 323 x 403 x 199 x 77 x 307 = 7348031198508

Therefore, the lowest common multiple of 646,403,796,924,921 is 7348031198508.

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.

646 x 403 x 796 x 924 x 921 = 176352748764192

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.

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

403 : 1, 13, 31, 403

796 : 1, 2, 4, 199, 398, 796

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,403,796,924,921, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

403:13x 31

796:2x 2x 199

924:2x 2x 3x 7x 11

921:3x 307

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 3 = 24

Therefore, the value for common factors is 24.

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 = 176352748764192/(1x24)

LCM = 176352748764192/24

LCM = 7348031198508

Thus, we can understand that the LCM of 646,403,796,924,921 is 7348031198508.
