Given numbers are 278, 905, 851, 311
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 905) = 251590
GCD(278, 905) = ( 278 x 905 ) / 251590
= 278 / 905
= 278
Step2:
LCM(1, 851) = 851
GCD(1, 851) = ( 1 x 851 ) / 851
= 1 / 851
= 1
Step3:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
So, Greatest Common Divisor of 278, 905, 851, 311 is 1
