Find LCM of 431,702,351,182,361 with Prime Factorization
| 2 | 431, 702, 351, 182, 361 |
| 3 | 431, 351, 351, 91, 361 |
| 3 | 431, 117, 117, 91, 361 |
| 3 | 431, 39, 39, 91, 361 |
| 13 | 431, 13, 13, 91, 361 |
| 431, 1, 1, 7, 361 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 431 x 1 x 1 x 7 x 361 = 764574174
Therefore, the lowest common multiple of 431,702,351,182,361 is 764574174.
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.
431 x 702 x 351 x 182 x 361 = 6977503911924
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.
431 : 1, 431
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
351 : 1, 3, 9, 13, 27, 39, 117, 351
182 : 1, 2, 7, 13, 14, 26, 91, 182
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,702,351,182,361, is 1.
Now, the common factors can be found like this.
431:431
702:2x 3x 3x 3x 13
351:3x 3x 3x 13
182:2x 7x 13
361:19x 19
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 3x 3x 13x 13 = 9126
Therefore, the value for common factors is 9126.
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 = 6977503911924/(1x9126)
LCM = 6977503911924/9126
LCM = 764574174
Thus, we can understand that the LCM of 431,702,351,182,361 is 764574174.
