GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(577, 819) = 472563
GCD(577, 819) = ( 577 x 819 ) / 472563
= 577 / 819
= 577
Step2:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 577, 819, 742, 438 is 1
