Given numbers are 987, 342, 388, 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, 342) = 112518
GCD(987, 342) = ( 987 x 342 ) / 112518
= 987 / 342
= 987
Step2:
LCM(3, 388) = 1164
GCD(3, 388) = ( 3 x 388 ) / 1164
= 3 / 388
= 3
Step3:
LCM(1, 131) = 131
GCD(1, 131) = ( 1 x 131 ) / 131
= 1 / 131
= 1
So, Greatest Common Divisor of 987, 342, 388, 131 is 1
