Find LCM of 861,171,182,341,558 with Prime Factorization
| 2 | 861, 171, 182, 341, 558 |
| 3 | 861, 171, 91, 341, 279 |
| 3 | 287, 57, 91, 341, 93 |
| 7 | 287, 19, 91, 341, 31 |
| 31 | 41, 19, 13, 341, 31 |
| 41, 19, 13, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 31 x 41 x 19 x 13 x 11 x 1 = 435116682
Therefore, the lowest common multiple of 861,171,182,341,558 is 435116682.
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.
861 x 171 x 182 x 341 x 558 = 5098697279676
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
171 : 1, 3, 9, 19, 57, 171
182 : 1, 2, 7, 13, 14, 26, 91, 182
341 : 1, 11, 31, 341
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,171,182,341,558, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
171:3x 3x 19
182:2x 7x 13
341:11x 31
558:2x 3x 3x 31
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 7x 31 = 11718
Therefore, the value for common factors is 11718.
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 = 5098697279676/(1x11718)
LCM = 5098697279676/11718
LCM = 435116682
Thus, we can understand that the LCM of 861,171,182,341,558 is 435116682.
