Given numbers are 391, 633, 98, 872

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

Apply this formula for all numbers.

Step1:

LCM(391, 633) = 247503

GCD(391, 633) = ( 391 x 633 ) / 247503

= 391 / 633

= 391

Step2:

LCM(1, 98) = 98

GCD(1, 98) = ( 1 x 98 ) / 98

= 1 / 98

= 1

Step3:

LCM(1, 872) = 872

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

= 1 / 872

= 1

So, Greatest Common Divisor of 391, 633, 98, 872 is 1
