Given numbers are 187,220,187,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,220,187,546 is 1021020.
Find LCM of 187,220,187,546 with Prime Factorization
| 2 | 187, 220, 187, 546 |
| 11 | 187, 110, 187, 273 |
| 17 | 17, 10, 17, 273 |
| 1, 10, 1, 273 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 1 x 10 x 1 x 273 = 1021020
Therefore, the lowest common multiple of 187,220,187,546 is 1021020.
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.
187 x 220 x 187 x 546 = 4200476280
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.
187 : 1, 11, 17, 187
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
187 : 1, 11, 17, 187
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,220,187,546, is 1.
Now, the common factors can be found like this.
187:11x 17
220:2x 2x 5x 11
187:11x 17
546:2x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 17 = 4114
Therefore, the value for common factors is 4114.
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 = 4200476280/(1x4114)
LCM = 4200476280/4114
LCM = 1021020
Thus, we can understand that the LCM of 187,220,187,546 is 1021020.
