Calculate the LCM of 171,249,131,393

Given numbers are 171,249,131,393

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

The LCM of 171,249,131,393 is 1859283.

Find LCM of 171,249,131,393 with Prime Factorization


3 171, 249, 131, 393
131 57, 83, 131, 131
57, 83, 1, 1

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

3 x 131 x 57 x 83 x 1 x 1 = 1859283

Therefore, the lowest common multiple of 171,249,131,393 is 1859283.

LCM Formula to Find Lowest Common Multiple of 171,249,131,393

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.

171 x 249 x 131 x 393 = 2192094657

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.

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

249 : 1, 3, 83, 249

131 : 1, 131

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,249,131,393, is 1.

Now, the common factors can be found like this.

171:3x 3x 19

249:3x 83

131:131

393:3x 131

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

3x 3x 131 = 1179

Therefore, the value for common factors is 1179.

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 = 2192094657/(1x1179)

LCM = 2192094657/1179

LCM = 1859283

Thus, we can understand that the LCM of 171,249,131,393 is 1859283.
