Given numbers are 930, 477, 561, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(930, 477) = 147870
GCD(930, 477) = ( 930 x 477 ) / 147870
= 930 / 477
= 930
Step2:
LCM(3, 561) = 561
GCD(3, 561) = ( 3 x 561 ) / 561
= 3 / 561
= 3
Step3:
LCM(3, 455) = 1365
GCD(3, 455) = ( 3 x 455 ) / 1365
= 3 / 455
= 3
So, Greatest Common Divisor of 930, 477, 561, 455 is 1
