Given numbers are 655, 561, 856, 869
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 561) = 367455
GCD(655, 561) = ( 655 x 561 ) / 367455
= 655 / 561
= 655
Step2:
LCM(1, 856) = 856
GCD(1, 856) = ( 1 x 856 ) / 856
= 1 / 856
= 1
Step3:
LCM(1, 869) = 869
GCD(1, 869) = ( 1 x 869 ) / 869
= 1 / 869
= 1
So, Greatest Common Divisor of 655, 561, 856, 869 is 1
