Given numbers are 695, 215, 211, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(695, 215) = 29885
GCD(695, 215) = ( 695 x 215 ) / 29885
= 695 / 215
= 695
Step2:
LCM(5, 211) = 1055
GCD(5, 211) = ( 5 x 211 ) / 1055
= 5 / 211
= 5
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 695, 215, 211, 561 is 1
