Given numbers are 745, 790, 217, 839

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

Apply this formula for all numbers.

Step1:

LCM(745, 790) = 117710

GCD(745, 790) = ( 745 x 790 ) / 117710

= 745 / 790

= 745

Step2:

LCM(5, 217) = 1085

GCD(5, 217) = ( 5 x 217 ) / 1085

= 5 / 217

= 5

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 745, 790, 217, 839 is 1
