GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(549, 530) = 290970
GCD(549, 530) = ( 549 x 530 ) / 290970
= 549 / 530
= 549
Step2:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
Step3:
LCM(1, 800) = 800
GCD(1, 800) = ( 1 x 800 ) / 800
= 1 / 800
= 1
So, Greatest Common Divisor of 549, 530, 285, 800 is 1
