Given numbers are 861,190,713,252
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,190,713,252 is 699838020.
Find LCM of 861,190,713,252 with Prime Factorization
| 2 | 861, 190, 713, 252 |
| 3 | 861, 95, 713, 126 |
| 7 | 287, 95, 713, 42 |
| 41, 95, 713, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 95 x 713 x 6 = 699838020
Therefore, the lowest common multiple of 861,190,713,252 is 699838020.
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.
861 x 190 x 713 x 252 = 29393196840
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
190 : 1, 2, 5, 10, 19, 38, 95, 190
713 : 1, 23, 31, 713
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,190,713,252, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
190:2x 5x 19
713:23x 31
252:2x 2x 3x 3x 7
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 7 = 42
Therefore, the value for common factors is 42.
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 = 29393196840/(1x42)
LCM = 29393196840/42
LCM = 699838020
Thus, we can understand that the LCM of 861,190,713,252 is 699838020.
