Given numbers are 247, 130, 837, 872

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

Apply this formula for all numbers.

Step1:

LCM(247, 130) = 2470

GCD(247, 130) = ( 247 x 130 ) / 2470

= 247 / 130

= 247

Step2:

LCM(13, 837) = 10881

GCD(13, 837) = ( 13 x 837 ) / 10881

= 13 / 837

= 13

Step3:

LCM(1, 872) = 872

GCD(1, 872) = ( 1 x 872 ) / 872

= 1 / 872

= 1

So, Greatest Common Divisor of 247, 130, 837, 872 is 1
