Given numbers are 203, 687, 945, 683
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(203, 687) = 139461
GCD(203, 687) = ( 203 x 687 ) / 139461
= 203 / 687
= 203
Step2:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
Step3:
LCM(1, 683) = 683
GCD(1, 683) = ( 1 x 683 ) / 683
= 1 / 683
= 1
So, Greatest Common Divisor of 203, 687, 945, 683 is 1
