Given numbers are 991, 530, 663, 939
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 530) = 525230
GCD(991, 530) = ( 991 x 530 ) / 525230
= 991 / 530
= 991
Step2:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
Step3:
LCM(1, 939) = 939
GCD(1, 939) = ( 1 x 939 ) / 939
= 1 / 939
= 1
So, Greatest Common Divisor of 991, 530, 663, 939 is 1
