Given numbers are 829,638,778,666

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

The LCM of 829,638,778,666 is 68512378374.

Find LCM of 829,638,778,666 with Prime Factorization

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

2 x 829 x 319 x 389 x 333 = 68512378374

Therefore, the lowest common multiple of 829,638,778,666 is 68512378374.

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.

829 x 638 x 778 x 666 = 274049513496

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.

829 : 1, 829

638 : 1, 2, 11, 22, 29, 58, 319, 638

778 : 1, 2, 389, 778

666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,638,778,666, is 1.

Now, the common factors can be found like this.

829:829

638:2x 11x 29

778:2x 389

666:2x 3x 3x 37

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 274049513496/(1x4)

LCM = 274049513496/4

LCM = 68512378374

Thus, we can understand that the LCM of 829,638,778,666 is 68512378374.
