Given numbers are 780,788,989,176

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

The LCM of 780,788,989,176 is 6686668560.

Find LCM of 780,788,989,176 with Prime Factorization

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

2 x 2 x 195 x 197 x 989 x 44 = 6686668560

Therefore, the lowest common multiple of 780,788,989,176 is 6686668560.

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.

780 x 788 x 989 x 176 = 106986696960

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

788 : 1, 2, 4, 197, 394, 788

989 : 1, 23, 43, 989

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,788,989,176, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

788:2x 2x 197

989:23x 43

176:2x 2x 2x 2x 11

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 2 = 16

Therefore, the value for common factors is 16.

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 = 106986696960/(1x16)

LCM = 106986696960/16

LCM = 6686668560

Thus, we can understand that the LCM of 780,788,989,176 is 6686668560.
