Given numbers are 890, 705, 399, 219

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

Apply this formula for all numbers.

Step1:

LCM(890, 705) = 125490

GCD(890, 705) = ( 890 x 705 ) / 125490

= 890 / 705

= 890

Step2:

LCM(5, 399) = 1995

GCD(5, 399) = ( 5 x 399 ) / 1995

= 5 / 399

= 5

Step3:

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

= 1 / 219

= 1

So, Greatest Common Divisor of 890, 705, 399, 219 is 1
