Given numbers are 990, 561, 109, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 561) = 16830
GCD(990, 561) = ( 990 x 561 ) / 16830
= 990 / 561
= 990
Step2:
LCM(33, 109) = 3597
GCD(33, 109) = ( 33 x 109 ) / 3597
= 33 / 109
= 33
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 990, 561, 109, 193 is 1
