Given numbers are 487, 140, 809, 801

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

Apply this formula for all numbers.

Step1:

LCM(487, 140) = 68180

GCD(487, 140) = ( 487 x 140 ) / 68180

= 487 / 140

= 487

Step2:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

Step3:

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

= 1 / 801

= 1

So, Greatest Common Divisor of 487, 140, 809, 801 is 1
