Given numbers are 817, 684, 115, 745

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

Apply this formula for all numbers.

Step1:

LCM(817, 684) = 29412

GCD(817, 684) = ( 817 x 684 ) / 29412

= 817 / 684

= 817

Step2:

LCM(19, 115) = 2185

GCD(19, 115) = ( 19 x 115 ) / 2185

= 19 / 115

= 19

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 817, 684, 115, 745 is 1
