Find LCM of 797,630,357,765 with Prime Factorization
| 3 | 797, 630, 357, 765 |
| 3 | 797, 210, 119, 255 |
| 5 | 797, 70, 119, 85 |
| 7 | 797, 14, 119, 17 |
| 17 | 797, 2, 17, 17 |
| 797, 2, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 17 x 797 x 2 x 1 x 1 = 8535870
Therefore, the lowest common multiple of 797,630,357,765 is 8535870.
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.
797 x 630 x 357 x 765 = 137128751550
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.
797 : 1, 797
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
357 : 1, 3, 7, 17, 21, 51, 119, 357
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,630,357,765, is 1.
Now, the common factors can be found like this.
797:797
630:2x 3x 3x 5x 7
357:3x 7x 17
765:3x 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.
3x 3x 3x 5x 7x 17 = 16065
Therefore, the value for common factors is 16065.
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 = 137128751550/(1x16065)
LCM = 137128751550/16065
LCM = 8535870
Thus, we can understand that the LCM of 797,630,357,765 is 8535870.
