Given numbers are 690,378,381,266,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,378,381,266,909 is 10594204110.
Find LCM of 690,378,381,266,909 with Prime Factorization
| 2 | 690, 378, 381, 266, 909 |
| 3 | 345, 189, 381, 133, 909 |
| 3 | 115, 63, 127, 133, 303 |
| 7 | 115, 21, 127, 133, 101 |
| 115, 3, 127, 19, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 115 x 3 x 127 x 19 x 101 = 10594204110
Therefore, the lowest common multiple of 690,378,381,266,909 is 10594204110.
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.
690 x 378 x 381 x 266 x 909 = 24027654921480
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
381 : 1, 3, 127, 381
266 : 1, 2, 7, 14, 19, 38, 133, 266
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,378,381,266,909, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
378:2x 3x 3x 3x 7
381:3x 127
266:2x 7x 19
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 3x 7 = 2268
Therefore, the value for common factors is 2268.
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 = 24027654921480/(1x2268)
LCM = 24027654921480/2268
LCM = 10594204110
Thus, we can understand that the LCM of 690,378,381,266,909 is 10594204110.
