Given numbers are 427, 133, 280, 381
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 133) = 8113
GCD(427, 133) = ( 427 x 133 ) / 8113
= 427 / 133
= 427
Step2:
LCM(7, 280) = 280
GCD(7, 280) = ( 7 x 280 ) / 280
= 7 / 280
= 7
Step3:
LCM(7, 381) = 2667
GCD(7, 381) = ( 7 x 381 ) / 2667
= 7 / 381
= 7
So, Greatest Common Divisor of 427, 133, 280, 381 is 1
