Calculate the LCM of 891,151,871,492

Given numbers are 891,151,871,492

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

The LCM of 891,151,871,492 is 19218374604.

Find LCM of 891,151,871,492 with Prime Factorization


3 891, 151, 871, 492
297, 151, 871, 164

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

3 x 297 x 151 x 871 x 164 = 19218374604

Therefore, the lowest common multiple of 891,151,871,492 is 19218374604.

LCM Formula to Find Lowest Common Multiple of 891,151,871,492

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.

891 x 151 x 871 x 492 = 57655123812

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.

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

151 : 1, 151

871 : 1, 13, 67, 871

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,151,871,492, is 1.

Now, the common factors can be found like this.

891:3x 3x 3x 3x 11

151:151

871:13x 67

492:2x 2x 3x 41

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

3 = 3

Therefore, the value for common factors is 3.

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 = 57655123812/(1x3)

LCM = 57655123812/3

LCM = 19218374604

Thus, we can understand that the LCM of 891,151,871,492 is 19218374604.
