Given numbers are 231, 245, 787, 126
The list of prime factors of all numbers are
Prime factors of 231 are 3 x 7 x 11
Prime factors of 245 are 5 x 7 x 7
Prime factors of 787 are 787
Prime factors of 126 are 2 x 3 x 3 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 231, 245, 787, 126
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 245) = 8085
GCD(231, 245) = ( 231 x 245 ) / 8085
= 231 / 245
= 231
Step2:
LCM(7, 787) = 5509
GCD(7, 787) = ( 7 x 787 ) / 5509
= 7 / 787
= 7
Step3:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
So, Greatest Common Divisor of 231, 245, 787, 126 is 1
