GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(693, 729) = 56133
GCD(693, 729) = ( 693 x 729 ) / 56133
= 693 / 729
= 693
Step2:
LCM(9, 245) = 2205
GCD(9, 245) = ( 9 x 245 ) / 2205
= 9 / 245
= 9
Step3:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
So, Greatest Common Divisor of 693, 729, 245, 122 is 1
