Given numbers are 310, 923, 211, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(310, 923) = 286130
GCD(310, 923) = ( 310 x 923 ) / 286130
= 310 / 923
= 310
Step2:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 310, 923, 211, 391 is 1
