Given numbers are 725, 812, 947, 871

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

Apply this formula for all numbers.

Step1:

LCM(725, 812) = 20300

GCD(725, 812) = ( 725 x 812 ) / 20300

= 725 / 812

= 725

Step2:

LCM(29, 947) = 27463

GCD(29, 947) = ( 29 x 947 ) / 27463

= 29 / 947

= 29

Step3:

LCM(1, 871) = 871

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

= 1 / 871

= 1

So, Greatest Common Divisor of 725, 812, 947, 871 is 1
