Find LCM of 765,876,731,438,228 with Prime Factorization
| 2 | 765, 876, 731, 438, 228 |
| 2 | 765, 438, 731, 219, 114 |
| 3 | 765, 219, 731, 219, 57 |
| 17 | 255, 73, 731, 73, 19 |
| 73 | 15, 73, 43, 73, 19 |
| 15, 1, 43, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 73 x 15 x 1 x 43 x 1 x 19 = 182501460
Therefore, the lowest common multiple of 765,876,731,438,228 is 182501460.
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.
765 x 876 x 731 x 438 x 228 = 48920611361760
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
731 : 1, 17, 43, 731
438 : 1, 2, 3, 6, 73, 146, 219, 438
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,876,731,438,228, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
876:2x 2x 3x 73
731:17x 43
438:2x 3x 73
228:2x 2x 3x 19
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 3x 3x 17x 73 = 268056
Therefore, the value for common factors is 268056.
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 = 48920611361760/(1x268056)
LCM = 48920611361760/268056
LCM = 182501460
Thus, we can understand that the LCM of 765,876,731,438,228 is 182501460.
