GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(279, 666) = 20646
GCD(279, 666) = ( 279 x 666 ) / 20646
= 279 / 666
= 279
Step2:
LCM(9, 523) = 4707
GCD(9, 523) = ( 9 x 523 ) / 4707
= 9 / 523
= 9
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 279, 666, 523, 455 is 1
