Given numbers are 967,969,990,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 967,969,990,170 is 309217590.
Find LCM of 967,969,990,170 with Prime Factorization
| 2 | 967, 969, 990, 170 |
| 3 | 967, 969, 495, 85 |
| 5 | 967, 323, 165, 85 |
| 17 | 967, 323, 33, 17 |
| 967, 19, 33, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 967 x 19 x 33 x 1 = 309217590
Therefore, the lowest common multiple of 967,969,990,170 is 309217590.
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.
967 x 969 x 990 x 170 = 157700970900
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.
967 : 1, 967
969 : 1, 3, 17, 19, 51, 57, 323, 969
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 967,969,990,170, is 1.
Now, the common factors can be found like this.
967:967
969:3x 17x 19
990:2x 3x 3x 5x 11
170:2x 5x 17
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 5x 17 = 510
Therefore, the value for common factors is 510.
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 = 157700970900/(1x510)
LCM = 157700970900/510
LCM = 309217590
Thus, we can understand that the LCM of 967,969,990,170 is 309217590.
