Given numbers are 628, 122, 786, 145

The list of prime factors of all numbers are

Prime factors of 628 are 2 x 2 x 157

Prime factors of 122 are 2 x 61

Prime factors of 786 are 2 x 3 x 131

Prime factors of 145 are 5 x 29

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

Given numbers are 628, 122, 786, 145

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

Apply this formula for all numbers.

Step1:

LCM(628, 122) = 38308

GCD(628, 122) = ( 628 x 122 ) / 38308

= 628 / 122

= 628

Step2:

LCM(2, 786) = 786

GCD(2, 786) = ( 2 x 786 ) / 786

= 2 / 786

= 2

Step3:

LCM(2, 145) = 290

GCD(2, 145) = ( 2 x 145 ) / 290

= 2 / 145

= 2

So, Greatest Common Divisor of 628, 122, 786, 145 is 1
