GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 221) = 45747
GCD(207, 221) = ( 207 x 221 ) / 45747
= 207 / 221
= 207
Step2:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
So, Greatest Common Divisor of 207, 221, 126 is 1
