Given numbers are 721, 316, 91, 458

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

Apply this formula for all numbers.

Step1:

LCM(721, 316) = 227836

GCD(721, 316) = ( 721 x 316 ) / 227836

= 721 / 316

= 721

Step2:

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

= 1 / 91

= 1

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 721, 316, 91, 458 is 1
