Find LCM of 762,805,686,195,144 with Prime Factorization
| 2 | 762, 805, 686, 195, 144 |
| 3 | 381, 805, 343, 195, 72 |
| 5 | 127, 805, 343, 65, 24 |
| 7 | 127, 161, 343, 13, 24 |
| 127, 23, 49, 13, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 127 x 23 x 49 x 13 x 24 = 9377812080
Therefore, the lowest common multiple of 762,805,686,195,144 is 9377812080.
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.
762 x 805 x 686 x 195 x 144 = 11816043220800
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
805 : 1, 5, 7, 23, 35, 115, 161, 805
686 : 1, 2, 7, 14, 49, 98, 343, 686
195 : 1, 3, 5, 13, 15, 39, 65, 195
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,805,686,195,144, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
805:5x 7x 23
686:2x 7x 7x 7
195:3x 5x 13
144:2x 2x 2x 2x 3x 3
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 7 = 1260
Therefore, the value for common factors is 1260.
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 = 11816043220800/(1x1260)
LCM = 11816043220800/1260
LCM = 9377812080
Thus, we can understand that the LCM of 762,805,686,195,144 is 9377812080.
