Given numbers are 689, 975, 889, 839
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 975) = 51675
GCD(689, 975) = ( 689 x 975 ) / 51675
= 689 / 975
= 689
Step2:
LCM(13, 889) = 11557
GCD(13, 889) = ( 13 x 889 ) / 11557
= 13 / 889
= 13
Step3:
LCM(1, 839) = 839
GCD(1, 839) = ( 1 x 839 ) / 839
= 1 / 839
= 1
So, Greatest Common Divisor of 689, 975, 889, 839 is 1
