Given numbers are 945, 685, 139, 422

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

Apply this formula for all numbers.

Step1:

LCM(945, 685) = 129465

GCD(945, 685) = ( 945 x 685 ) / 129465

= 945 / 685

= 945

Step2:

LCM(5, 139) = 695

GCD(5, 139) = ( 5 x 139 ) / 695

= 5 / 139

= 5

Step3:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

So, Greatest Common Divisor of 945, 685, 139, 422 is 1
