Given numbers are 139, 278, 120, 823

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

Apply this formula for all numbers.

Step1:

LCM(139, 278) = 278

GCD(139, 278) = ( 139 x 278 ) / 278

= 139 / 278

= 139

Step2:

LCM(139, 120) = 16680

GCD(139, 120) = ( 139 x 120 ) / 16680

= 139 / 120

= 139

Step3:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

So, Greatest Common Divisor of 139, 278, 120, 823 is 1
