Calculate the LCM of 243,771,492,192

Given numbers are 243,771,492,192

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

The LCM of 243,771,492,192 is 163871424.

Find LCM of 243,771,492,192 with Prime Factorization


2 243, 771, 492, 192
2 243, 771, 246, 96
3 243, 771, 123, 48
81, 257, 41, 16

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

2 x 2 x 3 x 81 x 257 x 41 x 16 = 163871424

Therefore, the lowest common multiple of 243,771,492,192 is 163871424.

LCM Formula to Find Lowest Common Multiple of 243,771,492,192

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.

243 x 771 x 492 x 192 = 17698113792

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.

243 : 1, 3, 9, 27, 81, 243

771 : 1, 3, 257, 771

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,771,492,192, is 3.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

771:3x 257

492:2x 2x 3x 41

192:2x 2x 2x 2x 2x 2x 3

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 17698113792/(3x36)

LCM = 17698113792/108

LCM = 163871424

Thus, we can understand that the LCM of 243,771,492,192 is 163871424.
