The list of prime factors of all numbers are
Prime factors of 871 are 13 x 67
Prime factors of 342 are 2 x 3 x 3 x 19
Prime factors of 747 are 3 x 3 x 83
Prime factors of 252 are 2 x 2 x 3 x 3 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 871, 342, 747, 252
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(871, 342) = 297882
GCD(871, 342) = ( 871 x 342 ) / 297882
= 871 / 342
= 871
Step2:
LCM(1, 747) = 747
GCD(1, 747) = ( 1 x 747 ) / 747
= 1 / 747
= 1
Step3:
LCM(1, 252) = 252
GCD(1, 252) = ( 1 x 252 ) / 252
= 1 / 252
= 1
So, Greatest Common Divisor of 871, 342, 747, 252 is 1
