Given numbers are 871, 473, 661, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(871, 473) = 411983
GCD(871, 473) = ( 871 x 473 ) / 411983
= 871 / 473
= 871
Step2:
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
= 1 / 661
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 871, 473, 661, 689 is 1
