Given numbers are 654, 256, 859, 380

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

Apply this formula for all numbers.

Step1:

LCM(654, 256) = 83712

GCD(654, 256) = ( 654 x 256 ) / 83712

= 654 / 256

= 654

Step2:

LCM(2, 859) = 1718

GCD(2, 859) = ( 2 x 859 ) / 1718

= 2 / 859

= 2

Step3:

LCM(1, 380) = 380

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

= 1 / 380

= 1

So, Greatest Common Divisor of 654, 256, 859, 380 is 1
