The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 155 are 5 x 31

Prime factors of 278 are 2 x 139

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

Given numbers are 385, 688, 155, 278

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

Apply this formula for all numbers.

Step1:

LCM(385, 688) = 264880

GCD(385, 688) = ( 385 x 688 ) / 264880

= 385 / 688

= 385

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 385, 688, 155, 278 is 1
