Given numbers are 857, 505, 25, 424

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

Apply this formula for all numbers.

Step1:

LCM(857, 505) = 432785

GCD(857, 505) = ( 857 x 505 ) / 432785

= 857 / 505

= 857

Step2:

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

= 1 / 25

= 1

Step3:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

So, Greatest Common Divisor of 857, 505, 25, 424 is 1
