Given numbers are 280, 865, 732, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 865) = 48440
GCD(280, 865) = ( 280 x 865 ) / 48440
= 280 / 865
= 280
Step2:
LCM(5, 732) = 3660
GCD(5, 732) = ( 5 x 732 ) / 3660
= 5 / 732
= 5
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 280, 865, 732, 805 is 1
