Given numbers are 992,662,978,495,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 992,662,978,495,987 is 8716223688480.
Find LCM of 992,662,978,495,987 with Prime Factorization
| 2 | 992, 662, 978, 495, 987 |
| 3 | 496, 331, 489, 495, 987 |
| 496, 331, 163, 165, 329 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 496 x 331 x 163 x 165 x 329 = 8716223688480
Therefore, the lowest common multiple of 992,662,978,495,987 is 8716223688480.
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.
992 x 662 x 978 x 495 x 987 = 313784052785280
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.
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
662 : 1, 2, 331, 662
978 : 1, 2, 3, 6, 163, 326, 489, 978
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 992,662,978,495,987, is 1.
Now, the common factors can be found like this.
992:2x 2x 2x 2x 2x 31
662:2x 331
978:2x 3x 163
495:3x 3x 5x 11
987:3x 7x 47
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 3 = 36
Therefore, the value for common factors is 36.
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 = 313784052785280/(1x36)
LCM = 313784052785280/36
LCM = 8716223688480
Thus, we can understand that the LCM of 992,662,978,495,987 is 8716223688480.
