Both of these numbers are divisible by 3 and 7. The factors of 105 is 21 x 5 and that of 147 is 21 x 7. So the LCM is 21 x 35 = 735.
189 = 3 x 3 x 3 x 7; 105 = 3 x 5 x 7. Common factors are 3 and 7 so LCM = product /HCF ie 189 x 105/21 = 945
The LCM is: 147
The LCM is 147.
The LCM is 441.
The LCM is 3969.
735
The lcm is 23520.
189 = 3 x 3 x 3 x 7; 105 = 3 x 5 x 7. Common factors are 3 and 7 so LCM = product /HCF ie 189 x 105/21 = 945
The LCM is: 147
Since 147 is a multiple of 21, it is automatically the LCM.
The LCM is 147.
The LCM is 441.
105/147 = 5/7
1.4
The LCM is 3969.
The LCM is: 105
The LCM is 294.
