Given numbers are 261, 151, 231, 325
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 151) = 39411
GCD(261, 151) = ( 261 x 151 ) / 39411
= 261 / 151
= 261
Step2:
LCM(1, 231) = 231
GCD(1, 231) = ( 1 x 231 ) / 231
= 1 / 231
= 1
Step3:
LCM(1, 325) = 325
GCD(1, 325) = ( 1 x 325 ) / 325
= 1 / 325
= 1
So, Greatest Common Divisor of 261, 151, 231, 325 is 1
