Find LCM of 630,791,794,836,255 with Prime Factorization
| 2 | 630, 791, 794, 836, 255 |
| 3 | 315, 791, 397, 418, 255 |
| 5 | 105, 791, 397, 418, 85 |
| 7 | 21, 791, 397, 418, 17 |
| 3, 113, 397, 418, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 3 x 113 x 397 x 418 x 17 = 200832827580
Therefore, the lowest common multiple of 630,791,794,836,255 is 200832827580.
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.
630 x 791 x 794 x 836 x 255 = 84349787583600
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
791 : 1, 7, 113, 791
794 : 1, 2, 397, 794
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,791,794,836,255, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
791:7x 113
794:2x 397
836:2x 2x 11x 19
255:3x 5x 17
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 7 = 420
Therefore, the value for common factors is 420.
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 = 84349787583600/(1x420)
LCM = 84349787583600/420
LCM = 200832827580
Thus, we can understand that the LCM of 630,791,794,836,255 is 200832827580.
