GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 979) = 165451
GCD(169, 979) = ( 169 x 979 ) / 165451
= 169 / 979
= 169
Step2:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
Step3:
LCM(1, 894) = 894
GCD(1, 894) = ( 1 x 894 ) / 894
= 1 / 894
= 1
So, Greatest Common Divisor of 169, 979, 661, 894 is 1
