GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 350) = 196350
GCD(561, 350) = ( 561 x 350 ) / 196350
= 561 / 350
= 561
Step2:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
So, Greatest Common Divisor of 561, 350, 203 is 1
