Given numbers are 721, 262, 352, 820

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 262 are 2 x 131

Prime factors of 352 are 2 x 2 x 2 x 2 x 2 x 11

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

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

Given numbers are 721, 262, 352, 820

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

Apply this formula for all numbers.

Step1:

LCM(721, 262) = 188902

GCD(721, 262) = ( 721 x 262 ) / 188902

= 721 / 262

= 721

Step2:

LCM(1, 352) = 352

GCD(1, 352) = ( 1 x 352 ) / 352

= 1 / 352

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 721, 262, 352, 820 is 1
