Given numbers are 308, 220, 985, 105

The list of prime factors of all numbers are

Prime factors of 308 are 2 x 2 x 7 x 11

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

Prime factors of 985 are 5 x 197

Prime factors of 105 are 3 x 5 x 7

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

Given numbers are 308, 220, 985, 105

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

Apply this formula for all numbers.

Step1:

LCM(308, 220) = 1540

GCD(308, 220) = ( 308 x 220 ) / 1540

= 308 / 220

= 308

Step2:

LCM(44, 985) = 43340

GCD(44, 985) = ( 44 x 985 ) / 43340

= 44 / 985

= 44

Step3:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

So, Greatest Common Divisor of 308, 220, 985, 105 is 1
