Calculate the LCM of 622,981,724,311

Given numbers are 622,981,724,311

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

The LCM of 622,981,724,311 is 220885884.

Find LCM of 622,981,724,311 with Prime Factorization


2 622, 981, 724, 311
311 311, 981, 362, 311
1, 981, 362, 1

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

2 x 311 x 1 x 981 x 362 x 1 = 220885884

Therefore, the lowest common multiple of 622,981,724,311 is 220885884.

LCM Formula to Find Lowest Common Multiple of 622,981,724,311

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.

622 x 981 x 724 x 311 = 137391019848

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.

622 : 1, 2, 311, 622

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

724 : 1, 2, 4, 181, 362, 724

311 : 1, 311

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,981,724,311, is 1.

Now, the common factors can be found like this.

622:2x 311

981:3x 3x 109

724:2x 2x 181

311:311

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

2x 311 = 622

Therefore, the value for common factors is 622.

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 = 137391019848/(1x622)

LCM = 137391019848/622

LCM = 220885884

Thus, we can understand that the LCM of 622,981,724,311 is 220885884.
