Given numbers are 436, 686, 46, 721

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

Apply this formula for all numbers.

Step1:

LCM(436, 686) = 149548

GCD(436, 686) = ( 436 x 686 ) / 149548

= 436 / 686

= 436

Step2:

LCM(2, 46) = 46

GCD(2, 46) = ( 2 x 46 ) / 46

= 2 / 46

= 2

Step3:

LCM(2, 721) = 1442

GCD(2, 721) = ( 2 x 721 ) / 1442

= 2 / 721

= 2

So, Greatest Common Divisor of 436, 686, 46, 721 is 1
