Given numbers are 991, 781, 442, 181
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 781) = 773971
GCD(991, 781) = ( 991 x 781 ) / 773971
= 991 / 781
= 991
Step2:
LCM(1, 442) = 442
GCD(1, 442) = ( 1 x 442 ) / 442
= 1 / 442
= 1
Step3:
LCM(1, 181) = 181
GCD(1, 181) = ( 1 x 181 ) / 181
= 1 / 181
= 1
So, Greatest Common Divisor of 991, 781, 442, 181 is 1
