If you mean the greatest prime factor of 210 it is 7.
Highest prime factor, indeed only prime factor, is 5
Prime factors of 210 = 2 x 3 x 5 x 7Prime factors of 147 = 3 x 7 x 7Common factors = 3 x 7 so the highest common factor is 21.
This is a LCM question, so factor all and find the highest power of each prime factor. 2 is prime 3 is prime 5 is prime 6 is [2 3] 7 is prime. LCM is [2] [3] [5] [7] so the answer is 210◄
2 x 3 x 5 x 7 = 210
