Given numbers are 577, 871, 81, 143

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

Apply this formula for all numbers.

Step1:

LCM(577, 871) = 502567

GCD(577, 871) = ( 577 x 871 ) / 502567

= 577 / 871

= 577

Step2:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

Step3:

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

= 1 / 143

= 1

So, Greatest Common Divisor of 577, 871, 81, 143 is 1
