Given numbers are 279, 309, 626, 631
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(279, 309) = 28737
GCD(279, 309) = ( 279 x 309 ) / 28737
= 279 / 309
= 279
Step2:
LCM(3, 626) = 1878
GCD(3, 626) = ( 3 x 626 ) / 1878
= 3 / 626
= 3
Step3:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
So, Greatest Common Divisor of 279, 309, 626, 631 is 1
