Given numbers are 689, 310, 871, 371
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 310) = 213590
GCD(689, 310) = ( 689 x 310 ) / 213590
= 689 / 310
= 689
Step2:
LCM(1, 871) = 871
GCD(1, 871) = ( 1 x 871 ) / 871
= 1 / 871
= 1
Step3:
LCM(1, 371) = 371
GCD(1, 371) = ( 1 x 371 ) / 371
= 1 / 371
= 1
So, Greatest Common Divisor of 689, 310, 871, 371 is 1
