Find LCM of 189,163,765,274,986 with Prime Factorization
| 2 | 189, 163, 765, 274, 986 |
| 3 | 189, 163, 765, 137, 493 |
| 3 | 63, 163, 255, 137, 493 |
| 17 | 21, 163, 85, 137, 493 |
| 21, 163, 5, 137, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 21 x 163 x 5 x 137 x 29 = 20807355870
Therefore, the lowest common multiple of 189,163,765,274,986 is 20807355870.
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 163 x 765 x 274 x 986 = 6367050896220
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
163 : 1, 163
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
274 : 1, 2, 137, 274
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,163,765,274,986, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
163:163
765:3x 3x 5x 17
274:2x 137
986:2x 17x 29
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 17 = 306
Therefore, the value for common factors is 306.
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 = 6367050896220/(1x306)
LCM = 6367050896220/306
LCM = 20807355870
Thus, we can understand that the LCM of 189,163,765,274,986 is 20807355870.
