Given numbers are 987, 231, 303, 131
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 231) = 10857
GCD(987, 231) = ( 987 x 231 ) / 10857
= 987 / 231
= 987
Step2:
LCM(21, 303) = 2121
GCD(21, 303) = ( 21 x 303 ) / 2121
= 21 / 303
= 21
Step3:
LCM(3, 131) = 393
GCD(3, 131) = ( 3 x 131 ) / 393
= 3 / 131
= 3
So, Greatest Common Divisor of 987, 231, 303, 131 is 1
