Given numbers are 821, 961, 853, 634

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

Apply this formula for all numbers.

Step1:

LCM(821, 961) = 788981

GCD(821, 961) = ( 821 x 961 ) / 788981

= 821 / 961

= 821

Step2:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 821, 961, 853, 634 is 1
