Given numbers are 155, 794, 308, 684

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 794 are 2 x 397

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

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 155, 794, 308, 684

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

Apply this formula for all numbers.

Step1:

LCM(155, 794) = 123070

GCD(155, 794) = ( 155 x 794 ) / 123070

= 155 / 794

= 155

Step2:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 155, 794, 308, 684 is 1
