Calculate the LCM of 198,558,427,672

Given numbers are 198,558,427,672

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

The LCM of 198,558,427,672 is 41934816.

Find LCM of 198,558,427,672 with Prime Factorization


2 198, 558, 427, 672
3 99, 279, 427, 336
3 33, 93, 427, 112
7 11, 31, 427, 112
11, 31, 61, 16

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

2 x 3 x 3 x 7 x 11 x 31 x 61 x 16 = 41934816

Therefore, the lowest common multiple of 198,558,427,672 is 41934816.

LCM Formula to Find Lowest Common Multiple of 198,558,427,672

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 558 x 427 x 672 = 31702720896

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

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

427 : 1, 7, 61, 427

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,558,427,672, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

558:2x 3x 3x 31

427:7x 61

672:2x 2x 2x 2x 2x 3x 7

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 3x 3x 7 = 756

Therefore, the value for common factors is 756.

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 = 31702720896/(1x756)

LCM = 31702720896/756

LCM = 41934816

Thus, we can understand that the LCM of 198,558,427,672 is 41934816.
