Given numbers are 381, 339, 278, 285
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 339) = 43053
GCD(381, 339) = ( 381 x 339 ) / 43053
= 381 / 339
= 381
Step2:
LCM(3, 278) = 834
GCD(3, 278) = ( 3 x 278 ) / 834
= 3 / 278
= 3
Step3:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
So, Greatest Common Divisor of 381, 339, 278, 285 is 1
