Given numbers are 796,976,156,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 796,976,156,978 is 1234681968.
Find LCM of 796,976,156,978 with Prime Factorization
2 | 796, 976, 156, 978 |
2 | 398, 488, 78, 489 |
3 | 199, 244, 39, 489 |
199, 244, 13, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 199 x 244 x 13 x 163 = 1234681968
Therefore, the lowest common multiple of 796,976,156,978 is 1234681968.
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.
796 x 976 x 156 x 978 = 118529468928
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.
796 : 1, 2, 4, 199, 398, 796
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
978 : 1, 2, 3, 6, 163, 326, 489, 978
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 796,976,156,978, is 2.
Now, the common factors can be found like this.
796:2x 2x 199
976:2x 2x 2x 2x 61
156:2x 2x 3x 13
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 118529468928/(2x48)
LCM = 118529468928/96
LCM = 1234681968
Thus, we can understand that the LCM of 796,976,156,978 is 1234681968.
