Find LCM of 177,405,405,538,402 with Prime Factorization
| 2 | 177, 405, 405, 538, 402 |
| 3 | 177, 405, 405, 269, 201 |
| 3 | 59, 135, 135, 269, 67 |
| 3 | 59, 45, 45, 269, 67 |
| 3 | 59, 15, 15, 269, 67 |
| 5 | 59, 5, 5, 269, 67 |
| 59, 1, 1, 269, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 5 x 59 x 1 x 1 x 269 x 67 = 861319170
Therefore, the lowest common multiple of 177,405,405,538,402 is 861319170.
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.
177 x 405 x 405 x 538 x 402 = 6279016749300
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.
177 : 1, 3, 59, 177
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
538 : 1, 2, 269, 538
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,405,405,538,402, is 1.
Now, the common factors can be found like this.
177:3x 59
405:3x 3x 3x 3x 5
405:3x 3x 3x 3x 5
538:2x 269
402:2x 3x 67
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 3x 3x 3x 5 = 7290
Therefore, the value for common factors is 7290.
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 = 6279016749300/(1x7290)
LCM = 6279016749300/7290
LCM = 861319170
Thus, we can understand that the LCM of 177,405,405,538,402 is 861319170.
