Given numbers are 687, 664, 969, 683
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 664) = 456168
GCD(687, 664) = ( 687 x 664 ) / 456168
= 687 / 664
= 687
Step2:
LCM(1, 969) = 969
GCD(1, 969) = ( 1 x 969 ) / 969
= 1 / 969
= 1
Step3:
LCM(1, 683) = 683
GCD(1, 683) = ( 1 x 683 ) / 683
= 1 / 683
= 1
So, Greatest Common Divisor of 687, 664, 969, 683 is 1
