Given numbers are 639, 465, 403, 112

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

Apply this formula for all numbers.

Step1:

LCM(639, 465) = 99045

GCD(639, 465) = ( 639 x 465 ) / 99045

= 639 / 465

= 639

Step2:

LCM(3, 403) = 1209

GCD(3, 403) = ( 3 x 403 ) / 1209

= 3 / 403

= 3

Step3:

LCM(1, 112) = 112

GCD(1, 112) = ( 1 x 112 ) / 112

= 1 / 112

= 1

So, Greatest Common Divisor of 639, 465, 403, 112 is 1
