Find LCM of 189,719,908,660,770 with Prime Factorization
| 2 | 189, 719, 908, 660, 770 |
| 2 | 189, 719, 454, 330, 385 |
| 3 | 189, 719, 227, 165, 385 |
| 5 | 63, 719, 227, 55, 385 |
| 7 | 63, 719, 227, 11, 77 |
| 11 | 9, 719, 227, 11, 11 |
| 9, 719, 227, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 9 x 719 x 227 x 1 x 1 = 6786396540
Therefore, the lowest common multiple of 189,719,908,660,770 is 6786396540.
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 719 x 908 x 660 x 770 = 62706304029600
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
719 : 1, 719
908 : 1, 2, 4, 227, 454, 908
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,719,908,660,770, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
719:719
908:2x 2x 227
660:2x 2x 3x 5x 11
770:2x 5x 7x 11
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 2x 3x 5x 7x 11 = 9240
Therefore, the value for common factors is 9240.
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 = 62706304029600/(1x9240)
LCM = 62706304029600/9240
LCM = 6786396540
Thus, we can understand that the LCM of 189,719,908,660,770 is 6786396540.
