Given numbers are 821, 990, 890, 777

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 890 are 2 x 5 x 89

Prime factors of 777 are 3 x 7 x 37

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 821, 990, 890, 777

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

Apply this formula for all numbers.

Step1:

LCM(821, 990) = 812790

GCD(821, 990) = ( 821 x 990 ) / 812790

= 821 / 990

= 821

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 821, 990, 890, 777 is 1
