Find LCM of 966,186,525,770,391 with Prime Factorization
| 2 | 966, 186, 525, 770, 391 |
| 3 | 483, 93, 525, 385, 391 |
| 5 | 161, 31, 175, 385, 391 |
| 7 | 161, 31, 35, 77, 391 |
| 23 | 23, 31, 5, 11, 391 |
| 1, 31, 5, 11, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 23 x 1 x 31 x 5 x 11 x 17 = 139997550
Therefore, the lowest common multiple of 966,186,525,770,391 is 139997550.
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 186 x 525 x 770 x 391 = 28399902993000
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
186 : 1, 2, 3, 6, 31, 62, 93, 186
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,186,525,770,391, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
186:2x 3x 31
525:3x 5x 5x 7
770:2x 5x 7x 11
391:17x 23
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 3x 5x 7x 7x 23 = 202860
Therefore, the value for common factors is 202860.
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 = 28399902993000/(1x202860)
LCM = 28399902993000/202860
LCM = 139997550
Thus, we can understand that the LCM of 966,186,525,770,391 is 139997550.
