GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(549, 111) = 20313
GCD(549, 111) = ( 549 x 111 ) / 20313
= 549 / 111
= 549
Step2:
LCM(3, 318) = 318
GCD(3, 318) = ( 3 x 318 ) / 318
= 3 / 318
= 3
Step3:
LCM(3, 691) = 2073
GCD(3, 691) = ( 3 x 691 ) / 2073
= 3 / 691
= 3
So, Greatest Common Divisor of 549, 111, 318, 691 is 1
