Calculate the LCM of 231,715,105,275

Given numbers are 231,715,105,275

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

The LCM of 231,715,105,275 is 75075.

Find LCM of 231,715,105,275 with Prime Factorization


3 231, 715, 105, 275
5 77, 715, 35, 275
7 77, 143, 7, 55
11 11, 143, 1, 55
1, 13, 1, 5

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

3 x 5 x 7 x 11 x 1 x 13 x 1 x 5 = 75075

Therefore, the lowest common multiple of 231,715,105,275 is 75075.

LCM Formula to Find Lowest Common Multiple of 231,715,105,275

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.

231 x 715 x 105 x 275 = 4769139375

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.

231 : 1, 3, 7, 11, 21, 33, 77, 231

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

105 : 1, 3, 5, 7, 15, 21, 35, 105

275 : 1, 5, 11, 25, 55, 275

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,715,105,275, is 1.

Now, the common factors can be found like this.

231:3x 7x 11

715:5x 11x 13

105:3x 5x 7

275:5x 5x 11

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 5x 7x 11x 11 = 63525

Therefore, the value for common factors is 63525.

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 = 4769139375/(1x63525)

LCM = 4769139375/63525

LCM = 75075

Thus, we can understand that the LCM of 231,715,105,275 is 75075.
