Given numbers are 579, 421, 257, 953

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

Apply this formula for all numbers.

Step1:

LCM(579, 421) = 243759

GCD(579, 421) = ( 579 x 421 ) / 243759

= 579 / 421

= 579

Step2:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

Step3:

LCM(1, 953) = 953

GCD(1, 953) = ( 1 x 953 ) / 953

= 1 / 953

= 1

So, Greatest Common Divisor of 579, 421, 257, 953 is 1
