Given numbers are 189,969,989,306
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,969,989,306 is 120750966.
Find LCM of 189,969,989,306 with Prime Factorization
| 3 | 189, 969, 989, 306 |
| 3 | 63, 323, 989, 102 |
| 17 | 21, 323, 989, 34 |
| 21, 19, 989, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 21 x 19 x 989 x 2 = 120750966
Therefore, the lowest common multiple of 189,969,989,306 is 120750966.
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.
189 x 969 x 989 x 306 = 55424693394
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
969 : 1, 3, 17, 19, 51, 57, 323, 969
989 : 1, 23, 43, 989
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,969,989,306, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
969:3x 17x 19
989:23x 43
306:2x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 17 = 459
Therefore, the value for common factors is 459.
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 = 55424693394/(1x459)
LCM = 55424693394/459
LCM = 120750966
Thus, we can understand that the LCM of 189,969,989,306 is 120750966.
