Given numbers are 865, 255, 343, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 255) = 44115
GCD(865, 255) = ( 865 x 255 ) / 44115
= 865 / 255
= 865
Step2:
LCM(5, 343) = 1715
GCD(5, 343) = ( 5 x 343 ) / 1715
= 5 / 343
= 5
Step3:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
So, Greatest Common Divisor of 865, 255, 343, 211 is 1
