Given numbers are 945, 961, 539, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 961) = 908145
GCD(945, 961) = ( 945 x 961 ) / 908145
= 945 / 961
= 945
Step2:
LCM(1, 539) = 539
GCD(1, 539) = ( 1 x 539 ) / 539
= 1 / 539
= 1
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 945, 961, 539, 991 is 1
