Given numbers are 425, 751, 421, 770

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

Apply this formula for all numbers.

Step1:

LCM(425, 751) = 319175

GCD(425, 751) = ( 425 x 751 ) / 319175

= 425 / 751

= 425

Step2:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 425, 751, 421, 770 is 1
