Given numbers are 187,221,702,735,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,221,702,735,678 is 3634320690.
Find LCM of 187,221,702,735,678 with Prime Factorization
| 2 | 187, 221, 702, 735, 678 |
| 3 | 187, 221, 351, 735, 339 |
| 13 | 187, 221, 117, 245, 113 |
| 17 | 187, 17, 9, 245, 113 |
| 11, 1, 9, 245, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 11 x 1 x 9 x 245 x 113 = 3634320690
Therefore, the lowest common multiple of 187,221,702,735,678 is 3634320690.
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 221 x 702 x 735 x 678 = 14457327704820
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
221 : 1, 13, 17, 221
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,221,702,735,678, is 1.
Now, the common factors can be found like this.
187:11x 17
221:13x 17
702:2x 3x 3x 3x 13
735:3x 5x 7x 7
678:2x 3x 113
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 13x 17 = 3978
Therefore, the value for common factors is 3978.
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 = 14457327704820/(1x3978)
LCM = 14457327704820/3978
LCM = 3634320690
Thus, we can understand that the LCM of 187,221,702,735,678 is 3634320690.
