Given numbers are 715,815,368,161

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

The LCM of 715,815,368,161 is 300219920.

Find LCM of 715,815,368,161 with Prime Factorization

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

5 x 23 x 143 x 163 x 16 x 7 = 300219920

Therefore, the lowest common multiple of 715,815,368,161 is 300219920.

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 815 x 368 x 161 = 34525290800

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

815 : 1, 5, 163, 815

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,815,368,161, is 1.

Now, the common factors can be found like this.

715:5x 11x 13

815:5x 163

368:2x 2x 2x 2x 23

161:7x 23

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

5x 23 = 115

Therefore, the value for common factors is 115.

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 = 34525290800/(1x115)

LCM = 34525290800/115

LCM = 300219920

Thus, we can understand that the LCM of 715,815,368,161 is 300219920.
