Given numbers are 251,830,180,172,186
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,830,180,172,186 is 4998670020.
Find LCM of 251,830,180,172,186 with Prime Factorization
| 2 | 251, 830, 180, 172, 186 |
| 2 | 251, 415, 90, 86, 93 |
| 3 | 251, 415, 45, 43, 93 |
| 5 | 251, 415, 15, 43, 31 |
| 251, 83, 3, 43, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 251 x 83 x 3 x 43 x 31 = 4998670020
Therefore, the lowest common multiple of 251,830,180,172,186 is 4998670020.
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.
251 x 830 x 180 x 172 x 186 = 1199680804800
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.
251 : 1, 251
830 : 1, 2, 5, 10, 83, 166, 415, 830
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
172 : 1, 2, 4, 43, 86, 172
186 : 1, 2, 3, 6, 31, 62, 93, 186
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,830,180,172,186, is 1.
Now, the common factors can be found like this.
251:251
830:2x 5x 83
180:2x 2x 3x 3x 5
172:2x 2x 43
186:2x 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 2x 2x 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 1199680804800/(1x240)
LCM = 1199680804800/240
LCM = 4998670020
Thus, we can understand that the LCM of 251,830,180,172,186 is 4998670020.
