Given numbers are 191,136,221,538,180
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 191,136,221,538,180 is 4087713240.
Find LCM of 191,136,221,538,180 with Prime Factorization
| 2 | 191, 136, 221, 538, 180 |
| 2 | 191, 68, 221, 269, 90 |
| 17 | 191, 34, 221, 269, 45 |
| 191, 2, 13, 269, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 191 x 2 x 13 x 269 x 45 = 4087713240
Therefore, the lowest common multiple of 191,136,221,538,180 is 4087713240.
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.
191 x 136 x 221 x 538 x 180 = 555929000640
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.
191 : 1, 191
136 : 1, 2, 4, 8, 17, 34, 68, 136
221 : 1, 13, 17, 221
538 : 1, 2, 269, 538
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,136,221,538,180, is 1.
Now, the common factors can be found like this.
191:191
136:2x 2x 2x 17
221:13x 17
538:2x 269
180:2x 2x 3x 3x 5
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 17 = 136
Therefore, the value for common factors is 136.
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 = 555929000640/(1x136)
LCM = 555929000640/136
LCM = 4087713240
Thus, we can understand that the LCM of 191,136,221,538,180 is 4087713240.
