Calculate the LCM of 387,654,981

Given numbers are 387,654,981

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

The LCM of 387,654,981 is 84366.

Find LCM of 387,654,981 with Prime Factorization


3 387, 654, 981
3 129, 218, 327
109 43, 218, 109
43, 2, 1

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

3 x 3 x 109 x 43 x 2 x 1 = 84366

Therefore, the lowest common multiple of 387,654,981 is 84366.

LCM Formula to Find Lowest Common Multiple of 387,654,981

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.

387 x 654 x 981 = 248289138

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.

387 : 1, 3, 9, 43, 129, 387

654 : 1, 2, 3, 6, 109, 218, 327, 654

981 : 1, 3, 9, 109, 327, 981

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,654,981, is 3.

Now, the common factors can be found like this.

387:3x 3x 43

654:2x 3x 109

981:3x 3x 109

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

3x 3x 109 = 981

Therefore, the value for common factors is 981.

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 = 248289138/(3x981)

LCM = 248289138/2943

LCM = 84366

Thus, we can understand that the LCM of 387,654,981 is 84366.
