Given numbers are 691,878,434,173

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

The LCM of 691,878,434,173 is 22776049618.

Find LCM of 691,878,434,173 with Prime Factorization

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

2 x 691 x 439 x 217 x 173 = 22776049618

Therefore, the lowest common multiple of 691,878,434,173 is 22776049618.

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.

691 x 878 x 434 x 173 = 45552099236

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.

691 : 1, 691

878 : 1, 2, 439, 878

434 : 1, 2, 7, 14, 31, 62, 217, 434

173 : 1, 173

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,878,434,173, is 1.

Now, the common factors can be found like this.

691:691

878:2x 439

434:2x 7x 31

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 45552099236/(1x2)

LCM = 45552099236/2

LCM = 22776049618

Thus, we can understand that the LCM of 691,878,434,173 is 22776049618.
