Given numbers are 920, 820, 87, 221

The list of prime factors of all numbers are

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

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

Prime factors of 87 are 3 x 29

Prime factors of 221 are 13 x 17

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

Given numbers are 920, 820, 87, 221

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

Apply this formula for all numbers.

Step1:

LCM(920, 820) = 37720

GCD(920, 820) = ( 920 x 820 ) / 37720

= 920 / 820

= 920

Step2:

LCM(20, 87) = 1740

GCD(20, 87) = ( 20 x 87 ) / 1740

= 20 / 87

= 20

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 920, 820, 87, 221 is 1
