Given numbers are 459, 782, 815, 380

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

Apply this formula for all numbers.

Step1:

LCM(459, 782) = 21114

GCD(459, 782) = ( 459 x 782 ) / 21114

= 459 / 782

= 459

Step2:

LCM(17, 815) = 13855

GCD(17, 815) = ( 17 x 815 ) / 13855

= 17 / 815

= 17

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 459, 782, 815, 380 is 1
