GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 649) = 180422
GCD(278, 649) = ( 278 x 649 ) / 180422
= 278 / 649
= 278
Step2:
LCM(1, 835) = 835
GCD(1, 835) = ( 1 x 835 ) / 835
= 1 / 835
= 1
Step3:
LCM(1, 585) = 585
GCD(1, 585) = ( 1 x 585 ) / 585
= 1 / 585
= 1
So, Greatest Common Divisor of 278, 649, 835, 585 is 1
