Given numbers are 715,505,890,171

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

The LCM of 715,505,890,171 is 2198080170.

Find LCM of 715,505,890,171 with Prime Factorization

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

5 x 143 x 101 x 178 x 171 = 2198080170

Therefore, the lowest common multiple of 715,505,890,171 is 2198080170.

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.

715 x 505 x 890 x 171 = 54952004250

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.

715 : 1, 5, 11, 13, 55, 65, 143, 715

505 : 1, 5, 101, 505

890 : 1, 2, 5, 10, 89, 178, 445, 890

171 : 1, 3, 9, 19, 57, 171

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,505,890,171, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

505:5x 101

890:2x 5x 89

171:3x 3x 19

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 54952004250/(1x25)

LCM = 54952004250/25

LCM = 2198080170

Thus, we can understand that the LCM of 715,505,890,171 is 2198080170.
