Given numbers are 439, 422, 173, 138
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(439, 422) = 185258
GCD(439, 422) = ( 439 x 422 ) / 185258
= 439 / 422
= 439
Step2:
LCM(1, 173) = 173
GCD(1, 173) = ( 1 x 173 ) / 173
= 1 / 173
= 1
Step3:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
So, Greatest Common Divisor of 439, 422, 173, 138 is 1
