Given numbers are 891, 166, 881, 821

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

Apply this formula for all numbers.

Step1:

LCM(891, 166) = 147906

GCD(891, 166) = ( 891 x 166 ) / 147906

= 891 / 166

= 891

Step2:

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

= 1 / 881

= 1

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 891, 166, 881, 821 is 1
