Given numbers are 122, 428, 618, 697
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(122, 428) = 26108
GCD(122, 428) = ( 122 x 428 ) / 26108
= 122 / 428
= 122
Step2:
LCM(2, 618) = 618
GCD(2, 618) = ( 2 x 618 ) / 618
= 2 / 618
= 2
Step3:
LCM(2, 697) = 1394
GCD(2, 697) = ( 2 x 697 ) / 1394
= 2 / 697
= 2
So, Greatest Common Divisor of 122, 428, 618, 697 is 1
