Given numbers are 865, 545, 394, 422
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 545) = 94285
GCD(865, 545) = ( 865 x 545 ) / 94285
= 865 / 545
= 865
Step2:
LCM(5, 394) = 1970
GCD(5, 394) = ( 5 x 394 ) / 1970
= 5 / 394
= 5
Step3:
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
= 1 / 422
= 1
So, Greatest Common Divisor of 865, 545, 394, 422 is 1
