Given numbers are 660, 689, 860, 437
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 689) = 454740
GCD(660, 689) = ( 660 x 689 ) / 454740
= 660 / 689
= 660
Step2:
LCM(1, 860) = 860
GCD(1, 860) = ( 1 x 860 ) / 860
= 1 / 860
= 1
Step3:
LCM(1, 437) = 437
GCD(1, 437) = ( 1 x 437 ) / 437
= 1 / 437
= 1
So, Greatest Common Divisor of 660, 689, 860, 437 is 1
