Prime factors of 284 are 2 x 2 x 71
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 813, 840, 765, 284
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 840) = 227640
GCD(813, 840) = ( 813 x 840 ) / 227640
= 813 / 840
= 813
Step2:
LCM(3, 765) = 765
GCD(3, 765) = ( 3 x 765 ) / 765
= 3 / 765
= 3
Step3:
LCM(3, 284) = 852
GCD(3, 284) = ( 3 x 284 ) / 852
= 3 / 284
= 3
So, Greatest Common Divisor of 813, 840, 765, 284 is 1
