GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(279, 628) = 175212
GCD(279, 628) = ( 279 x 628 ) / 175212
= 279 / 628
= 279
Step2:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 279, 628, 417, 561 is 1
