Given numbers are 815, 485, 122, 364
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 485) = 79055
GCD(815, 485) = ( 815 x 485 ) / 79055
= 815 / 485
= 815
Step2:
LCM(5, 122) = 610
GCD(5, 122) = ( 5 x 122 ) / 610
= 5 / 122
= 5
Step3:
LCM(1, 364) = 364
GCD(1, 364) = ( 1 x 364 ) / 364
= 1 / 364
= 1
So, Greatest Common Divisor of 815, 485, 122, 364 is 1
