Calculate the LCM of 931,561,867,789

Given numbers are 931,561,867,789

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

The LCM of 931,561,867,789 is 2335163061.

Find LCM of 931,561,867,789 with Prime Factorization


3 931, 561, 867, 789
17 931, 187, 289, 263
931, 11, 17, 263

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

3 x 17 x 931 x 11 x 17 x 263 = 2335163061

Therefore, the lowest common multiple of 931,561,867,789 is 2335163061.

LCM Formula to Find Lowest Common Multiple of 931,561,867,789

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.

931 x 561 x 867 x 789 = 357279948333

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.

931 : 1, 7, 19, 49, 133, 931

561 : 1, 3, 11, 17, 33, 51, 187, 561

867 : 1, 3, 17, 51, 289, 867

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,561,867,789, is 1.

Now, the common factors can be found like this.

931:7x 7x 19

561:3x 11x 17

867:3x 17x 17

789:3x 263

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 17 = 153

Therefore, the value for common factors is 153.

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 = 357279948333/(1x153)

LCM = 357279948333/153

LCM = 2335163061

Thus, we can understand that the LCM of 931,561,867,789 is 2335163061.
