Given numbers are 665,779,646,78

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

The LCM of 665,779,646,78 is 36153390.

Find LCM of 665,779,646,78 with Prime Factorization

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

2 x 19 x 35 x 41 x 17 x 39 = 36153390

Therefore, the lowest common multiple of 665,779,646,78 is 36153390.

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.

665 x 779 x 646 x 78 = 26102747580

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

779 : 1, 19, 41, 779

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

78 : 1, 2, 3, 6, 13, 26, 39, 78

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,779,646,78, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

779:19x 41

646:2x 17x 19

78:2x 3x 13

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

2x 19x 19 = 722

Therefore, the value for common factors is 722.

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 = 26102747580/(1x722)

LCM = 26102747580/722

LCM = 36153390

Thus, we can understand that the LCM of 665,779,646,78 is 36153390.
