Given numbers are 991, 965, 423, 531
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 965) = 956315
GCD(991, 965) = ( 991 x 965 ) / 956315
= 991 / 965
= 991
Step2:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
Step3:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
So, Greatest Common Divisor of 991, 965, 423, 531 is 1
