Given numbers are 855, 912, 355, 903
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 912) = 13680
GCD(855, 912) = ( 855 x 912 ) / 13680
= 855 / 912
= 855
Step2:
LCM(57, 355) = 20235
GCD(57, 355) = ( 57 x 355 ) / 20235
= 57 / 355
= 57
Step3:
LCM(1, 903) = 903
GCD(1, 903) = ( 1 x 903 ) / 903
= 1 / 903
= 1
So, Greatest Common Divisor of 855, 912, 355, 903 is 1
