Given numbers are 820, 721, 262

The list of prime factors of all numbers are

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

Prime factors of 721 are 7 x 103

Prime factors of 262 are 2 x 131

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

Given numbers are 820, 721, 262

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

Apply this formula for all numbers.

Step1:

LCM(820, 721) = 591220

GCD(820, 721) = ( 820 x 721 ) / 591220

= 820 / 721

= 820

Step2:

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

= 1 / 262

= 1

So, Greatest Common Divisor of 820, 721, 262 is 1
