Given numbers are 813, 261, 609, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 261) = 70731
GCD(813, 261) = ( 813 x 261 ) / 70731
= 813 / 261
= 813
Step2:
LCM(3, 609) = 609
GCD(3, 609) = ( 3 x 609 ) / 609
= 3 / 609
= 3
Step3:
LCM(3, 787) = 2361
GCD(3, 787) = ( 3 x 787 ) / 2361
= 3 / 787
= 3
So, Greatest Common Divisor of 813, 261, 609, 787 is 1
