Calculate the LCM of 991,218,109

Given numbers are 991,218,109

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

The LCM of 991,218,109 is 216038.

Find LCM of 991,218,109 with Prime Factorization


109 991, 218, 109
991, 2, 1

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

109 x 991 x 2 x 1 = 216038

Therefore, the lowest common multiple of 991,218,109 is 216038.

LCM Formula to Find Lowest Common Multiple of 991,218,109

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.

991 x 218 x 109 = 23548142

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.

991 : 1, 991

218 : 1, 2, 109, 218

109 : 1, 109

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,218,109, is 1.

Now, the common factors can be found like this.

991:991

218:2x 109

109:109

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

109 = 109

Therefore, the value for common factors is 109.

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 = 23548142/(1x109)

LCM = 23548142/109

LCM = 216038

Thus, we can understand that the LCM of 991,218,109 is 216038.
