Given numbers are 220, 208, 955, 780

The list of prime factors of all numbers are

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

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 955 are 5 x 191

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

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

Given numbers are 220, 208, 955, 780

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

Apply this formula for all numbers.

Step1:

LCM(220, 208) = 11440

GCD(220, 208) = ( 220 x 208 ) / 11440

= 220 / 208

= 220

Step2:

LCM(4, 955) = 3820

GCD(4, 955) = ( 4 x 955 ) / 3820

= 4 / 955

= 4

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 220, 208, 955, 780 is 1
