Given numbers are 660, 839, 464, 689
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 839) = 553740
GCD(660, 839) = ( 660 x 839 ) / 553740
= 660 / 839
= 660
Step2:
LCM(1, 464) = 464
GCD(1, 464) = ( 1 x 464 ) / 464
= 1 / 464
= 1
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 660, 839, 464, 689 is 1
