Given numbers are 381, 591, 157, 521
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 591) = 75057
GCD(381, 591) = ( 381 x 591 ) / 75057
= 381 / 591
= 381
Step2:
LCM(3, 157) = 471
GCD(3, 157) = ( 3 x 157 ) / 471
= 3 / 157
= 3
Step3:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
So, Greatest Common Divisor of 381, 591, 157, 521 is 1
