GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 472) = 121304
GCD(257, 472) = ( 257 x 472 ) / 121304
= 257 / 472
= 257
Step2:
LCM(1, 292) = 292
GCD(1, 292) = ( 1 x 292 ) / 292
= 1 / 292
= 1
Step3:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
So, Greatest Common Divisor of 257, 472, 292, 648 is 1
