Given numbers are 620, 266, 471, 661

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 266 are 2 x 7 x 19

Prime factors of 471 are 3 x 157

Prime factors of 661 are 661

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

Given numbers are 620, 266, 471, 661

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

Apply this formula for all numbers.

Step1:

LCM(620, 266) = 82460

GCD(620, 266) = ( 620 x 266 ) / 82460

= 620 / 266

= 620

Step2:

LCM(2, 471) = 942

GCD(2, 471) = ( 2 x 471 ) / 942

= 2 / 471

= 2

Step3:

LCM(1, 661) = 661

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

= 1 / 661

= 1

So, Greatest Common Divisor of 620, 266, 471, 661 is 1
