Given numbers are 487, 764, 620, 811

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

Apply this formula for all numbers.

Step1:

LCM(487, 764) = 372068

GCD(487, 764) = ( 487 x 764 ) / 372068

= 487 / 764

= 487

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

So, Greatest Common Divisor of 487, 764, 620, 811 is 1
