Given numbers are 487, 820, 428

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

Apply this formula for all numbers.

Step1:

LCM(487, 820) = 399340

GCD(487, 820) = ( 487 x 820 ) / 399340

= 487 / 820

= 487

Step2:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 487, 820, 428 is 1
