Given numbers are 254, 521, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(254, 521) = 132334
GCD(254, 521) = ( 254 x 521 ) / 132334
= 254 / 521
= 254
Step2:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 254, 521, 261 is 1
