Given numbers are 231, 406, 156, 620
The list of prime factors of all numbers are
Prime factors of 231 are 3 x 7 x 11
Prime factors of 406 are 2 x 7 x 29
Prime factors of 156 are 2 x 2 x 3 x 13
Prime factors of 620 are 2 x 2 x 5 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 231, 406, 156, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 406) = 13398
GCD(231, 406) = ( 231 x 406 ) / 13398
= 231 / 406
= 231
Step2:
LCM(7, 156) = 1092
GCD(7, 156) = ( 7 x 156 ) / 1092
= 7 / 156
= 7
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 231, 406, 156, 620 is 1
