Find LCM of 775,703,786,225,640 with Prime Factorization
2 | 775, 703, 786, 225, 640 |
3 | 775, 703, 393, 225, 320 |
5 | 775, 703, 131, 75, 320 |
5 | 155, 703, 131, 15, 64 |
31, 703, 131, 3, 64 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 31 x 703 x 131 x 3 x 64 = 82220630400
Therefore, the lowest common multiple of 775,703,786,225,640 is 82220630400.
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.
775 x 703 x 786 x 225 x 640 = 61665472800000
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.
775 : 1, 5, 25, 31, 155, 775
703 : 1, 19, 37, 703
786 : 1, 2, 3, 6, 131, 262, 393, 786
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,703,786,225,640, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
703:19x 37
786:2x 3x 131
225:3x 3x 5x 5
640:2x 2x 2x 2x 2x 2x 2x 5
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 5x 5x 5 = 750
Therefore, the value for common factors is 750.
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 = 61665472800000/(1x750)
LCM = 61665472800000/750
LCM = 82220630400
Thus, we can understand that the LCM of 775,703,786,225,640 is 82220630400.
