Given numbers are 215, 427, 111, 220

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 427 are 7 x 61

Prime factors of 111 are 3 x 37

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 215, 427, 111, 220

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

Apply this formula for all numbers.

Step1:

LCM(215, 427) = 91805

GCD(215, 427) = ( 215 x 427 ) / 91805

= 215 / 427

= 215

Step2:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 215, 427, 111, 220 is 1
