Given numbers are 505, 686, 850, 220

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 850 are 2 x 5 x 5 x 17

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

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

Given numbers are 505, 686, 850, 220

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

Apply this formula for all numbers.

Step1:

LCM(505, 686) = 346430

GCD(505, 686) = ( 505 x 686 ) / 346430

= 505 / 686

= 505

Step2:

LCM(1, 850) = 850

GCD(1, 850) = ( 1 x 850 ) / 850

= 1 / 850

= 1

Step3:

LCM(1, 220) = 220

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

= 1 / 220

= 1

So, Greatest Common Divisor of 505, 686, 850, 220 is 1
