Given numbers are 311, 488, 673, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(311, 488) = 151768
GCD(311, 488) = ( 311 x 488 ) / 151768
= 311 / 488
= 311
Step2:
LCM(1, 673) = 673
GCD(1, 673) = ( 1 x 673 ) / 673
= 1 / 673
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 311, 488, 673, 638 is 1
