GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(565, 105) = 11865
GCD(565, 105) = ( 565 x 105 ) / 11865
= 565 / 105
= 565
Step2:
LCM(5, 215) = 215
GCD(5, 215) = ( 5 x 215 ) / 215
= 5 / 215
= 5
Step3:
LCM(5, 690) = 690
GCD(5, 690) = ( 5 x 690 ) / 690
= 5 / 690
= 5
So, Greatest Common Divisor of 565, 105, 215, 690 is 5
