Given numbers are 820, 662, 623, 661

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 662 are 2 x 331

Prime factors of 623 are 7 x 89

Prime factors of 661 are 661

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

Given numbers are 820, 662, 623, 661

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

Apply this formula for all numbers.

Step1:

LCM(820, 662) = 271420

GCD(820, 662) = ( 820 x 662 ) / 271420

= 820 / 662

= 820

Step2:

LCM(2, 623) = 1246

GCD(2, 623) = ( 2 x 623 ) / 1246

= 2 / 623

= 2

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 820, 662, 623, 661 is 1
