Given numbers are 969,101,669,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 969,101,669,909 is 65474361.
Find LCM of 969,101,669,909 with Prime Factorization
| 3 | 969, 101, 669, 909 |
| 101 | 323, 101, 223, 303 |
| 323, 1, 223, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 101 x 323 x 1 x 223 x 3 = 65474361
Therefore, the lowest common multiple of 969,101,669,909 is 65474361.
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.
969 x 101 x 669 x 909 = 59516194149
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.
969 : 1, 3, 17, 19, 51, 57, 323, 969
101 : 1, 101
669 : 1, 3, 223, 669
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 969,101,669,909, is 1.
Now, the common factors can be found like this.
969:3x 17x 19
101:101
669:3x 223
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.
3x 3x 101 = 909
Therefore, the value for common factors is 909.
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 = 59516194149/(1x909)
LCM = 59516194149/909
LCM = 65474361
Thus, we can understand that the LCM of 969,101,669,909 is 65474361.
