Given numbers are 243, 112, 781, 139

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

Apply this formula for all numbers.

Step1:

LCM(243, 112) = 27216

GCD(243, 112) = ( 243 x 112 ) / 27216

= 243 / 112

= 243

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 139) = 139

GCD(1, 139) = ( 1 x 139 ) / 139

= 1 / 139

= 1

So, Greatest Common Divisor of 243, 112, 781, 139 is 1
