Calculate the LCM of 198,136,386,163

Given numbers are 198,136,386,163

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

The LCM of 198,136,386,163 is 423563976.

Find LCM of 198,136,386,163 with Prime Factorization


2 198, 136, 386, 163
99, 68, 193, 163

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

2 x 99 x 68 x 193 x 163 = 423563976

Therefore, the lowest common multiple of 198,136,386,163 is 423563976.

LCM Formula to Find Lowest Common Multiple of 198,136,386,163

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.

198 x 136 x 386 x 163 = 1694255904

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

136 : 1, 2, 4, 8, 17, 34, 68, 136

386 : 1, 2, 193, 386

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,136,386,163, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

136:2x 2x 2x 17

386:2x 193

163:163

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 1694255904/(1x4)

LCM = 1694255904/4

LCM = 423563976

Thus, we can understand that the LCM of 198,136,386,163 is 423563976.
