Given numbers are 208, 988, 654, 111

The list of prime factors of all numbers are

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

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 654 are 2 x 3 x 109

Prime factors of 111 are 3 x 37

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

Given numbers are 208, 988, 654, 111

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

Apply this formula for all numbers.

Step1:

LCM(208, 988) = 3952

GCD(208, 988) = ( 208 x 988 ) / 3952

= 208 / 988

= 208

Step2:

LCM(52, 654) = 17004

GCD(52, 654) = ( 52 x 654 ) / 17004

= 52 / 654

= 52

Step3:

LCM(2, 111) = 222

GCD(2, 111) = ( 2 x 111 ) / 222

= 2 / 111

= 2

So, Greatest Common Divisor of 208, 988, 654, 111 is 1
