GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(279, 570) = 53010
GCD(279, 570) = ( 279 x 570 ) / 53010
= 279 / 570
= 279
Step2:
LCM(3, 331) = 993
GCD(3, 331) = ( 3 x 331 ) / 993
= 3 / 331
= 3
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 279, 570, 331, 815 is 1
