Given numbers are 791,173,947,173

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

The LCM of 791,173,947,173 is 129590321.

Find LCM of 791,173,947,173 with Prime Factorization

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

173 x 791 x 1 x 947 x 1 = 129590321

Therefore, the lowest common multiple of 791,173,947,173 is 129590321.

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.

791 x 173 x 947 x 173 = 22419125533

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.

791 : 1, 7, 113, 791

173 : 1, 173

947 : 1, 947

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,173,947,173, is 1.

Now, the common factors can be found like this.

791:7x 113

173:173

947:947

173:173

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

173 = 173

Therefore, the value for common factors is 173.

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 = 22419125533/(1x173)

LCM = 22419125533/173

LCM = 129590321

Thus, we can understand that the LCM of 791,173,947,173 is 129590321.
