Given numbers are 722, 380, 19, 220

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

Apply this formula for all numbers.

Step1:

LCM(722, 380) = 7220

GCD(722, 380) = ( 722 x 380 ) / 7220

= 722 / 380

= 722

Step2:

LCM(38, 19) = 38

GCD(38, 19) = ( 38 x 19 ) / 38

= 38 / 19

= 38

Step3:

LCM(19, 220) = 4180

GCD(19, 220) = ( 19 x 220 ) / 4180

= 19 / 220

= 19

So, Greatest Common Divisor of 722, 380, 19, 220 is 1
