Calculate the LCM of 988,111,129,221

Given numbers are 988,111,129,221

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

The LCM of 988,111,129,221 is 80167308.

Find LCM of 988,111,129,221 with Prime Factorization


3 988, 111, 129, 221
13 988, 37, 43, 221
76, 37, 43, 17

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

3 x 13 x 76 x 37 x 43 x 17 = 80167308

Therefore, the lowest common multiple of 988,111,129,221 is 80167308.

LCM Formula to Find Lowest Common Multiple of 988,111,129,221

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.

988 x 111 x 129 x 221 = 3126525012

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.

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

111 : 1, 3, 37, 111

129 : 1, 3, 43, 129

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,111,129,221, is 1.

Now, the common factors can be found like this.

988:2x 2x 13x 19

111:3x 37

129:3x 43

221:13x 17

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

3x 13 = 39

Therefore, the value for common factors is 39.

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 = 3126525012/(1x39)

LCM = 3126525012/39

LCM = 80167308

Thus, we can understand that the LCM of 988,111,129,221 is 80167308.
