GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(319, 865) = 275935
GCD(319, 865) = ( 319 x 865 ) / 275935
= 319 / 865
= 319
Step2:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 319, 865, 640, 385 is 1
