Given numbers are 345, 650, 636, 661

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 650 are 2 x 5 x 5 x 13

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 661 are 661

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

Given numbers are 345, 650, 636, 661

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

Apply this formula for all numbers.

Step1:

LCM(345, 650) = 44850

GCD(345, 650) = ( 345 x 650 ) / 44850

= 345 / 650

= 345

Step2:

LCM(5, 636) = 3180

GCD(5, 636) = ( 5 x 636 ) / 3180

= 5 / 636

= 5

Step3:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

So, Greatest Common Divisor of 345, 650, 636, 661 is 1
