Given numbers are 711, 720, 555, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(711, 720) = 56880
GCD(711, 720) = ( 711 x 720 ) / 56880
= 711 / 720
= 711
Step2:
LCM(9, 555) = 1665
GCD(9, 555) = ( 9 x 555 ) / 1665
= 9 / 555
= 9
Step3:
LCM(3, 865) = 2595
GCD(3, 865) = ( 3 x 865 ) / 2595
= 3 / 865
= 3
So, Greatest Common Divisor of 711, 720, 555, 865 is 1
