Calculate the LCM of 285,995,975,170

Given numbers are 285,995,975,170

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

The LCM of 285,995,975,170 is 125340150.

Find LCM of 285,995,975,170 with Prime Factorization


3 285, 995, 975, 170
5 95, 995, 325, 170
19, 199, 65, 34

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

3 x 5 x 19 x 199 x 65 x 34 = 125340150

Therefore, the lowest common multiple of 285,995,975,170 is 125340150.

LCM Formula to Find Lowest Common Multiple of 285,995,975,170

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.

285 x 995 x 975 x 170 = 47002556250

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.

285 : 1, 3, 5, 15, 19, 57, 95, 285

995 : 1, 5, 199, 995

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

170 : 1, 2, 5, 10, 17, 34, 85, 170

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,995,975,170, is 5.

Now, the common factors can be found like this.

285:3x 5x 19

995:5x 199

975:3x 5x 5x 13

170:2x 5x 17

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

3x 5x 5 = 75

Therefore, the value for common factors is 75.

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 = 47002556250/(5x75)

LCM = 47002556250/375

LCM = 125340150

Thus, we can understand that the LCM of 285,995,975,170 is 125340150.
