Given numbers are 610, 988, 661, 628

The list of prime factors of all numbers are

Prime factors of 610 are 2 x 5 x 61

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

Prime factors of 661 are 661

Prime factors of 628 are 2 x 2 x 157

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

Given numbers are 610, 988, 661, 628

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

Apply this formula for all numbers.

Step1:

LCM(610, 988) = 301340

GCD(610, 988) = ( 610 x 988 ) / 301340

= 610 / 988

= 610

Step2:

LCM(2, 661) = 1322

GCD(2, 661) = ( 2 x 661 ) / 1322

= 2 / 661

= 2

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 610, 988, 661, 628 is 1
