Given numbers are 397,378,169,306
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,378,169,306 is 431139618.
Find LCM of 397,378,169,306 with Prime Factorization
| 2 | 397, 378, 169, 306 |
| 3 | 397, 189, 169, 153 |
| 3 | 397, 63, 169, 51 |
| 397, 21, 169, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 397 x 21 x 169 x 17 = 431139618
Therefore, the lowest common multiple of 397,378,169,306 is 431139618.
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.
397 x 378 x 169 x 306 = 7760513124
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.
397 : 1, 397
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
169 : 1, 13, 169
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,378,169,306, is 1.
Now, the common factors can be found like this.
397:397
378:2x 3x 3x 3x 7
169:13x 13
306:2x 3x 3x 17
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 3 = 18
Therefore, the value for common factors is 18.
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 = 7760513124/(1x18)
LCM = 7760513124/18
LCM = 431139618
Thus, we can understand that the LCM of 397,378,169,306 is 431139618.
