GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 474) = 88638
GCD(561, 474) = ( 561 x 474 ) / 88638
= 561 / 474
= 561
Step2:
LCM(3, 192) = 192
GCD(3, 192) = ( 3 x 192 ) / 192
= 3 / 192
= 3
Step3:
LCM(3, 225) = 225
GCD(3, 225) = ( 3 x 225 ) / 225
= 3 / 225
= 3
So, Greatest Common Divisor of 561, 474, 192, 225 is 3
