The LCM of 178,548,325,221,137 is 269465300.
Find LCM of 178,548,325,221,137 with Prime Factorization
| 2 | 178, 548, 325, 221, 137 |
| 13 | 89, 274, 325, 221, 137 |
| 137 | 89, 274, 25, 17, 137 |
| 89, 2, 25, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 137 x 89 x 2 x 25 x 17 x 1 = 269465300
Therefore, the lowest common multiple of 178,548,325,221,137 is 269465300.
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.
178 x 548 x 325 x 221 x 137 = 959835398600
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.
178 : 1, 2, 89, 178
548 : 1, 2, 4, 137, 274, 548
325 : 1, 5, 13, 25, 65, 325
221 : 1, 13, 17, 221
137 : 1, 137
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,548,325,221,137, is 1.
Now, the common factors can be found like this.
178:2x 89
548:2x 2x 137
325:5x 5x 13
221:13x 17
137:137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 137 = 3562
Therefore, the value for common factors is 3562.
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 = 959835398600/(1x3562)
LCM = 959835398600/3562
LCM = 269465300
Thus, we can understand that the LCM of 178,548,325,221,137 is 269465300.
