Given numbers are 165, 681, 464, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 681) = 37455
GCD(165, 681) = ( 165 x 681 ) / 37455
= 165 / 681
= 165
Step2:
LCM(3, 464) = 1392
GCD(3, 464) = ( 3 x 464 ) / 1392
= 3 / 464
= 3
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 165, 681, 464, 685 is 1
