GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(347, 247) = 85709
GCD(347, 247) = ( 347 x 247 ) / 85709
= 347 / 247
= 347
Step2:
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
= 1 / 18
= 1
Step3:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
So, Greatest Common Divisor of 347, 247, 18, 311 is 1
