Given numbers are 276, 381, 257, 445
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(276, 381) = 35052
GCD(276, 381) = ( 276 x 381 ) / 35052
= 276 / 381
= 276
Step2:
LCM(3, 257) = 771
GCD(3, 257) = ( 3 x 257 ) / 771
= 3 / 257
= 3
Step3:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
So, Greatest Common Divisor of 276, 381, 257, 445 is 1
