Find LCM of 916,789,812,145,285 with Prime Factorization
| 2 | 916, 789, 812, 145, 285 |
| 2 | 458, 789, 406, 145, 285 |
| 3 | 229, 789, 203, 145, 285 |
| 5 | 229, 263, 203, 145, 95 |
| 29 | 229, 263, 203, 29, 19 |
| 229, 263, 7, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 29 x 229 x 263 x 7 x 1 x 19 = 13937732340
Therefore, the lowest common multiple of 916,789,812,145,285 is 13937732340.
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.
916 x 789 x 812 x 145 x 285 = 24251654271600
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.
916 : 1, 2, 4, 229, 458, 916
789 : 1, 3, 263, 789
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
145 : 1, 5, 29, 145
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,789,812,145,285, is 1.
Now, the common factors can be found like this.
916:2x 2x 229
789:3x 263
812:2x 2x 7x 29
145:5x 29
285:3x 5x 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 3x 5x 29 = 1740
Therefore, the value for common factors is 1740.
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 = 24251654271600/(1x1740)
LCM = 24251654271600/1740
LCM = 13937732340
Thus, we can understand that the LCM of 916,789,812,145,285 is 13937732340.
