Given numbers are 138, 987, 401, 587

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(138, 987) = 45402

GCD(138, 987) = ( 138 x 987 ) / 45402

= 138 / 987

= 138

Step2:

LCM(3, 401) = 1203

GCD(3, 401) = ( 3 x 401 ) / 1203

= 3 / 401

= 3

Step3:

LCM(1, 587) = 587

GCD(1, 587) = ( 1 x 587 ) / 587

= 1 / 587

= 1

So, Greatest Common Divisor of 138, 987, 401, 587 is 1
