GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(748, 424) = 79288
GCD(748, 424) = ( 748 x 424 ) / 79288
= 748 / 424
= 748
Step2:
LCM(4, 255) = 1020
GCD(4, 255) = ( 4 x 255 ) / 1020
= 4 / 255
= 4
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 748, 424, 255, 891 is 1
