Given numbers are 872, 639, 955, 836

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

Apply this formula for all numbers.

Step1:

LCM(872, 639) = 557208

GCD(872, 639) = ( 872 x 639 ) / 557208

= 872 / 639

= 872

Step2:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

Step3:

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

= 1 / 836

= 1

So, Greatest Common Divisor of 872, 639, 955, 836 is 1
