Given numbers are 897, 457, 865, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 457) = 409929
GCD(897, 457) = ( 897 x 457 ) / 409929
= 897 / 457
= 897
Step2:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 897, 457, 865, 455 is 1
