Find LCM of 966,375,168,989 with Prime Factorization
| 2 | 966, 375, 168, 989 |
| 3 | 483, 375, 84, 989 |
| 7 | 161, 125, 28, 989 |
| 23 | 23, 125, 4, 989 |
| 1, 125, 4, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 1 x 125 x 4 x 43 = 20769000
Therefore, the lowest common multiple of 966,375,168,989 is 20769000.
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.
966 x 375 x 168 x 989 = 60188562000
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.
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
375 : 1, 3, 5, 15, 25, 75, 125, 375
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,375,168,989, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
375:3x 5x 5x 5
168:2x 2x 2x 3x 7
989:23x 43
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 3x 7x 23 = 2898
Therefore, the value for common factors is 2898.
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 = 60188562000/(1x2898)
LCM = 60188562000/2898
LCM = 20769000
Thus, we can understand that the LCM of 966,375,168,989 is 20769000.
