Given numbers are 427, 122, 671, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 122) = 854
GCD(427, 122) = ( 427 x 122 ) / 854
= 427 / 122
= 427
Step2:
LCM(61, 671) = 671
GCD(61, 671) = ( 61 x 671 ) / 671
= 61 / 671
= 61
Step3:
LCM(61, 689) = 42029
GCD(61, 689) = ( 61 x 689 ) / 42029
= 61 / 689
= 61
So, Greatest Common Divisor of 427, 122, 671, 689 is 1
