Given numbers are 186, 671, 682, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(186, 671) = 124806
GCD(186, 671) = ( 186 x 671 ) / 124806
= 186 / 671
= 186
Step2:
LCM(1, 682) = 682
GCD(1, 682) = ( 1 x 682 ) / 682
= 1 / 682
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 186, 671, 682, 689 is 1
