Given numbers are 777, 721, 523, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(777, 721) = 80031
GCD(777, 721) = ( 777 x 721 ) / 80031
= 777 / 721
= 777
Step2:
LCM(7, 523) = 3661
GCD(7, 523) = ( 7 x 523 ) / 3661
= 7 / 523
= 7
Step3:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
So, Greatest Common Divisor of 777, 721, 523, 122 is 1
