Given numbers are 577, 976, 517, 420

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

Apply this formula for all numbers.

Step1:

LCM(577, 976) = 563152

GCD(577, 976) = ( 577 x 976 ) / 563152

= 577 / 976

= 577

Step2:

LCM(1, 517) = 517

GCD(1, 517) = ( 1 x 517 ) / 517

= 1 / 517

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 577, 976, 517, 420 is 1
