Given numbers are 255, 246, 338, 390
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 246) = 20910
GCD(255, 246) = ( 255 x 246 ) / 20910
= 255 / 246
= 255
Step2:
LCM(3, 338) = 1014
GCD(3, 338) = ( 3 x 338 ) / 1014
= 3 / 338
= 3
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 255, 246, 338, 390 is 1
