Given numbers are 961, 114, 981, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(961, 114) = 109554
GCD(961, 114) = ( 961 x 114 ) / 109554
= 961 / 114
= 961
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 961, 114, 981, 221 is 1
