Given numbers are 220, 206, 515, 772

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 206 are 2 x 103

Prime factors of 515 are 5 x 103

Prime factors of 772 are 2 x 2 x 193

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

Given numbers are 220, 206, 515, 772

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

Apply this formula for all numbers.

Step1:

LCM(220, 206) = 22660

GCD(220, 206) = ( 220 x 206 ) / 22660

= 220 / 206

= 220

Step2:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 220, 206, 515, 772 is 1
