Given numbers are 639,372,996,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,372,996,288 is 52612704.
Find LCM of 639,372,996,288 with Prime Factorization
2 | 639, 372, 996, 288 |
2 | 639, 186, 498, 144 |
3 | 639, 93, 249, 72 |
3 | 213, 31, 83, 24 |
71, 31, 83, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 71 x 31 x 83 x 8 = 52612704
Therefore, the lowest common multiple of 639,372,996,288 is 52612704.
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.
639 x 372 x 996 x 288 = 68186064384
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.
639 : 1, 3, 9, 71, 213, 639
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,372,996,288, is 3.
Now, the common factors can be found like this.
639:3x 3x 71
372:2x 2x 3x 31
996:2x 2x 3x 83
288:2x 2x 2x 2x 2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 68186064384/(3x432)
LCM = 68186064384/1296
LCM = 52612704
Thus, we can understand that the LCM of 639,372,996,288 is 52612704.
