GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(248, 648) = 20088
GCD(248, 648) = ( 248 x 648 ) / 20088
= 248 / 648
= 248
Step2:
LCM(8, 290) = 1160
GCD(8, 290) = ( 8 x 290 ) / 1160
= 8 / 290
= 8
Step3:
LCM(2, 904) = 904
GCD(2, 904) = ( 2 x 904 ) / 904
= 2 / 904
= 2
So, Greatest Common Divisor of 248, 648, 290, 904 is 2
