Given numbers are 989,293,327,978,318
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,293,327,978,318 is 1637212810962.
Find LCM of 989,293,327,978,318 with Prime Factorization
| 2 | 989, 293, 327, 978, 318 |
| 3 | 989, 293, 327, 489, 159 |
| 989, 293, 109, 163, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 989 x 293 x 109 x 163 x 53 = 1637212810962
Therefore, the lowest common multiple of 989,293,327,978,318 is 1637212810962.
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.
989 x 293 x 327 x 978 x 318 = 29469830597316
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.
989 : 1, 23, 43, 989
293 : 1, 293
327 : 1, 3, 109, 327
978 : 1, 2, 3, 6, 163, 326, 489, 978
318 : 1, 2, 3, 6, 53, 106, 159, 318
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,293,327,978,318, is 1.
Now, the common factors can be found like this.
989:23x 43
293:293
327:3x 109
978:2x 3x 163
318:2x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 29469830597316/(1x18)
LCM = 29469830597316/18
LCM = 1637212810962
Thus, we can understand that the LCM of 989,293,327,978,318 is 1637212810962.
