GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(983, 243) = 238869
GCD(983, 243) = ( 983 x 243 ) / 238869
= 983 / 243
= 983
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 793) = 793
GCD(1, 793) = ( 1 x 793 ) / 793
= 1 / 793
= 1
So, Greatest Common Divisor of 983, 243, 644, 793 is 1
