Given numbers are 220, 855, 660, 274

The list of prime factors of all numbers are

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

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 274 are 2 x 137

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

Given numbers are 220, 855, 660, 274

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

Apply this formula for all numbers.

Step1:

LCM(220, 855) = 37620

GCD(220, 855) = ( 220 x 855 ) / 37620

= 220 / 855

= 220

Step2:

LCM(5, 660) = 660

GCD(5, 660) = ( 5 x 660 ) / 660

= 5 / 660

= 5

Step3:

LCM(5, 274) = 1370

GCD(5, 274) = ( 5 x 274 ) / 1370

= 5 / 274

= 5

So, Greatest Common Divisor of 220, 855, 660, 274 is 1
