Given numbers are 428, 928, 81, 970

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

Apply this formula for all numbers.

Step1:

LCM(428, 928) = 99296

GCD(428, 928) = ( 428 x 928 ) / 99296

= 428 / 928

= 428

Step2:

LCM(4, 81) = 324

GCD(4, 81) = ( 4 x 81 ) / 324

= 4 / 81

= 4

Step3:

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

= 1 / 970

= 1

So, Greatest Common Divisor of 428, 928, 81, 970 is 1
