Given numbers are 820, 217, 410, 197

The list of prime factors of all numbers are

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

Prime factors of 217 are 7 x 31

Prime factors of 410 are 2 x 5 x 41

Prime factors of 197 are 197

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

Given numbers are 820, 217, 410, 197

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

Apply this formula for all numbers.

Step1:

LCM(820, 217) = 177940

GCD(820, 217) = ( 820 x 217 ) / 177940

= 820 / 217

= 820

Step2:

LCM(1, 410) = 410

GCD(1, 410) = ( 1 x 410 ) / 410

= 1 / 410

= 1

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 820, 217, 410, 197 is 1
