The LCM of 251,988,912,543,978 is 87796679568.
Find LCM of 251,988,912,543,978 with Prime Factorization
| 2 | 251, 988, 912, 543, 978 |
| 2 | 251, 494, 456, 543, 489 |
| 3 | 251, 247, 228, 543, 489 |
| 19 | 251, 247, 76, 181, 163 |
| 251, 13, 4, 181, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 251 x 13 x 4 x 181 x 163 = 87796679568
Therefore, the lowest common multiple of 251,988,912,543,978 is 87796679568.
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.
251 x 988 x 912 x 543 x 978 = 120105857649024
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.
251 : 1, 251
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
543 : 1, 3, 181, 543
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,988,912,543,978, is 1.
Now, the common factors can be found like this.
251:251
988:2x 2x 13x 19
912:2x 2x 2x 2x 3x 19
543:3x 181
978:2x 3x 163
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 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 120105857649024/(1x1368)
LCM = 120105857649024/1368
LCM = 87796679568
Thus, we can understand that the LCM of 251,988,912,543,978 is 87796679568.
