Find LCM of 834,171,988,508,765 with Prime Factorization
| 2 | 834, 171, 988, 508, 765 |
| 2 | 417, 171, 494, 254, 765 |
| 3 | 417, 171, 247, 127, 765 |
| 3 | 139, 57, 247, 127, 255 |
| 19 | 139, 19, 247, 127, 85 |
| 139, 1, 13, 127, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 139 x 1 x 13 x 127 x 85 = 13342490460
Therefore, the lowest common multiple of 834,171,988,508,765 is 13342490460.
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.
834 x 171 x 988 x 508 x 765 = 54757580847840
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
171 : 1, 3, 9, 19, 57, 171
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
508 : 1, 2, 4, 127, 254, 508
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 834,171,988,508,765, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
171:3x 3x 19
988:2x 2x 13x 19
508:2x 2x 127
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.
2x 2x 2x 3x 3x 3x 19 = 4104
Therefore, the value for common factors is 4104.
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 = 54757580847840/(1x4104)
LCM = 54757580847840/4104
LCM = 13342490460
Thus, we can understand that the LCM of 834,171,988,508,765 is 13342490460.
