Find LCM of 796,792,121,642,221 with Prime Factorization
2 | 796, 792, 121, 642, 221 |
2 | 398, 396, 121, 321, 221 |
3 | 199, 198, 121, 321, 221 |
11 | 199, 66, 121, 107, 221 |
199, 6, 11, 107, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 199 x 6 x 11 x 107 x 221 = 40996520136
Therefore, the lowest common multiple of 796,792,121,642,221 is 40996520136.
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.
796 x 792 x 121 x 642 x 221 = 10823081315904
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.
796 : 1, 2, 4, 199, 398, 796
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
121 : 1, 11, 121
642 : 1, 2, 3, 6, 107, 214, 321, 642
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 796,792,121,642,221, is 1.
Now, the common factors can be found like this.
796:2x 2x 199
792:2x 2x 2x 3x 3x 11
121:11x 11
642:2x 3x 107
221:13x 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 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 10823081315904/(1x264)
LCM = 10823081315904/264
LCM = 40996520136
Thus, we can understand that the LCM of 796,792,121,642,221 is 40996520136.
