Given numbers are 689, 161, 137, 575
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 161) = 110929
GCD(689, 161) = ( 689 x 161 ) / 110929
= 689 / 161
= 689
Step2:
LCM(1, 137) = 137
GCD(1, 137) = ( 1 x 137 ) / 137
= 1 / 137
= 1
Step3:
LCM(1, 575) = 575
GCD(1, 575) = ( 1 x 575 ) / 575
= 1 / 575
= 1
So, Greatest Common Divisor of 689, 161, 137, 575 is 1
