Given numbers are 820, 470, 535, 771

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 470 are 2 x 5 x 47

Prime factors of 535 are 5 x 107

Prime factors of 771 are 3 x 257

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

Given numbers are 820, 470, 535, 771

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

Apply this formula for all numbers.

Step1:

LCM(820, 470) = 38540

GCD(820, 470) = ( 820 x 470 ) / 38540

= 820 / 470

= 820

Step2:

LCM(10, 535) = 1070

GCD(10, 535) = ( 10 x 535 ) / 1070

= 10 / 535

= 10

Step3:

LCM(5, 771) = 3855

GCD(5, 771) = ( 5 x 771 ) / 3855

= 5 / 771

= 5

So, Greatest Common Divisor of 820, 470, 535, 771 is 1
