Given numbers are 277, 390, 505, 196

The list of prime factors of all numbers are

Prime factors of 277 are 277

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 505 are 5 x 101

Prime factors of 196 are 2 x 2 x 7 x 7

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

Given numbers are 277, 390, 505, 196

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

Apply this formula for all numbers.

Step1:

LCM(277, 390) = 108030

GCD(277, 390) = ( 277 x 390 ) / 108030

= 277 / 390

= 277

Step2:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

Step3:

LCM(1, 196) = 196

GCD(1, 196) = ( 1 x 196 ) / 196

= 1 / 196

= 1

So, Greatest Common Divisor of 277, 390, 505, 196 is 1
