Calculate the LCM of 788,561,988,283

Given numbers are 788,561,988,283

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

The LCM of 788,561,988,283 is 30900995268.

Find LCM of 788,561,988,283 with Prime Factorization


2 788, 561, 988, 283
2 394, 561, 494, 283
197, 561, 247, 283

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

2 x 2 x 197 x 561 x 247 x 283 = 30900995268

Therefore, the lowest common multiple of 788,561,988,283 is 30900995268.

LCM Formula to Find Lowest Common Multiple of 788,561,988,283

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.

788 x 561 x 988 x 283 = 123603981072

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.

788 : 1, 2, 4, 197, 394, 788

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

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

283 : 1, 283

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,561,988,283, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

561:3x 11x 17

988:2x 2x 13x 19

283:283

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 123603981072/(1x4)

LCM = 123603981072/4

LCM = 30900995268

Thus, we can understand that the LCM of 788,561,988,283 is 30900995268.
