Given numbers are 682,856,420,902,663

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

The LCM of 682,856,420,902,663 is 277711313880.

Find LCM of 682,856,420,902,663 with Prime Factorization

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

2 x 2 x 3 x 11 x 31 x 214 x 35 x 41 x 221 = 277711313880

Therefore, the lowest common multiple of 682,856,420,902,663 is 277711313880.

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.

682 x 856 x 420 x 902 x 663 = 146631573728640

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.

682 : 1, 2, 11, 22, 31, 62, 341, 682

856 : 1, 2, 4, 8, 107, 214, 428, 856

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

902 : 1, 2, 11, 22, 41, 82, 451, 902

663 : 1, 3, 13, 17, 39, 51, 221, 663

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,856,420,902,663, is 1.

Now, the common factors can be found like this.

682:2x 11x 31

856:2x 2x 2x 107

420:2x 2x 3x 5x 7

902:2x 11x 41

663:3x 13x 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 3x 11 = 528

Therefore, the value for common factors is 528.

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 = 146631573728640/(1x528)

LCM = 146631573728640/528

LCM = 277711313880

Thus, we can understand that the LCM of 682,856,420,902,663 is 277711313880.
