Given numbers are 221, 351, 521, 158
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 351) = 5967
GCD(221, 351) = ( 221 x 351 ) / 5967
= 221 / 351
= 221
Step2:
LCM(13, 521) = 6773
GCD(13, 521) = ( 13 x 521 ) / 6773
= 13 / 521
= 13
Step3:
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
= 1 / 158
= 1
So, Greatest Common Divisor of 221, 351, 521, 158 is 1
