Given numbers are 316, 649, 138, 871

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

Apply this formula for all numbers.

Step1:

LCM(316, 649) = 205084

GCD(316, 649) = ( 316 x 649 ) / 205084

= 316 / 649

= 316

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 316, 649, 138, 871 is 1
