Given numbers are 821, 861, 197, 837

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

Apply this formula for all numbers.

Step1:

LCM(821, 861) = 706881

GCD(821, 861) = ( 821 x 861 ) / 706881

= 821 / 861

= 821

Step2:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

Step3:

LCM(1, 837) = 837

GCD(1, 837) = ( 1 x 837 ) / 837

= 1 / 837

= 1

So, Greatest Common Divisor of 821, 861, 197, 837 is 1
