Given numbers are 831, 505, 750, 220

The list of prime factors of all numbers are

Prime factors of 831 are 3 x 277

Prime factors of 505 are 5 x 101

Prime factors of 750 are 2 x 3 x 5 x 5 x 5

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 831, 505, 750, 220

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

Apply this formula for all numbers.

Step1:

LCM(831, 505) = 419655

GCD(831, 505) = ( 831 x 505 ) / 419655

= 831 / 505

= 831

Step2:

LCM(1, 750) = 750

GCD(1, 750) = ( 1 x 750 ) / 750

= 1 / 750

= 1

Step3:

LCM(1, 220) = 220

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

= 1 / 220

= 1

So, Greatest Common Divisor of 831, 505, 750, 220 is 1
