Given numbers are 721, 618, 389, 162

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

Apply this formula for all numbers.

Step1:

LCM(721, 618) = 4326

GCD(721, 618) = ( 721 x 618 ) / 4326

= 721 / 618

= 721

Step2:

LCM(103, 389) = 40067

GCD(103, 389) = ( 103 x 389 ) / 40067

= 103 / 389

= 103

Step3:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 721, 618, 389, 162 is 1
