Given numbers are 554, 981, 561, 454
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(554, 981) = 543474
GCD(554, 981) = ( 554 x 981 ) / 543474
= 554 / 981
= 554
Step2:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
Step3:
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
= 1 / 454
= 1
So, Greatest Common Divisor of 554, 981, 561, 454 is 1
