Given numbers are 117,285,378,321,954
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 117,285,378,321,954 is 2647392930.
Find LCM of 117,285,378,321,954 with Prime Factorization
| 2 | 117, 285, 378, 321, 954 |
| 3 | 117, 285, 189, 321, 477 |
| 3 | 39, 95, 63, 107, 159 |
| 13, 95, 21, 107, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 95 x 21 x 107 x 53 = 2647392930
Therefore, the lowest common multiple of 117,285,378,321,954 is 2647392930.
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.
117 x 285 x 378 x 321 x 954 = 3859898891940
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.
117 : 1, 3, 9, 13, 39, 117
285 : 1, 3, 5, 15, 19, 57, 95, 285
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
321 : 1, 3, 107, 321
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,285,378,321,954, is 3.
Now, the common factors can be found like this.
117:3x 3x 13
285:3x 5x 19
378:2x 3x 3x 3x 7
321:3x 107
954:2x 3x 3x 53
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 3x 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 3859898891940/(3x486)
LCM = 3859898891940/1458
LCM = 2647392930
Thus, we can understand that the LCM of 117,285,378,321,954 is 2647392930.
