GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(421, 981) = 413001
GCD(421, 981) = ( 421 x 981 ) / 413001
= 421 / 981
= 421
Step2:
LCM(1, 493) = 493
GCD(1, 493) = ( 1 x 493 ) / 493
= 1 / 493
= 1
Step3:
LCM(1, 523) = 523
GCD(1, 523) = ( 1 x 523 ) / 523
= 1 / 523
= 1
So, Greatest Common Divisor of 421, 981, 493, 523 is 1
