Given numbers are 655, 238, 220, 822

The list of prime factors of all numbers are

Prime factors of 655 are 5 x 131

Prime factors of 238 are 2 x 7 x 17

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

Prime factors of 822 are 2 x 3 x 137

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

Given numbers are 655, 238, 220, 822

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

Apply this formula for all numbers.

Step1:

LCM(655, 238) = 155890

GCD(655, 238) = ( 655 x 238 ) / 155890

= 655 / 238

= 655

Step2:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

Step3:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

So, Greatest Common Divisor of 655, 238, 220, 822 is 1
