Given numbers are 965,984,998,771,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 965,984,998,771,690 is 2800811730840.
Find LCM of 965,984,998,771,690 with Prime Factorization
| 2 | 965, 984, 998, 771, 690 |
| 3 | 965, 492, 499, 771, 345 |
| 5 | 965, 164, 499, 257, 115 |
| 193, 164, 499, 257, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 193 x 164 x 499 x 257 x 23 = 2800811730840
Therefore, the lowest common multiple of 965,984,998,771,690 is 2800811730840.
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.
965 x 984 x 998 x 771 x 690 = 504146111551200
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.
965 : 1, 5, 193, 965
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
998 : 1, 2, 499, 998
771 : 1, 3, 257, 771
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 965,984,998,771,690, is 1.
Now, the common factors can be found like this.
965:5x 193
984:2x 2x 2x 3x 41
998:2x 499
771:3x 257
690:2x 3x 5x 23
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 504146111551200/(1x180)
LCM = 504146111551200/180
LCM = 2800811730840
Thus, we can understand that the LCM of 965,984,998,771,690 is 2800811730840.
