Given numbers are 798, 315, 689, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(798, 315) = 11970
GCD(798, 315) = ( 798 x 315 ) / 11970
= 798 / 315
= 798
Step2:
LCM(21, 689) = 14469
GCD(21, 689) = ( 21 x 689 ) / 14469
= 21 / 689
= 21
Step3:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
So, Greatest Common Divisor of 798, 315, 689, 122 is 1
