Given numbers are 399, 257, 379, 371
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 257) = 102543
GCD(399, 257) = ( 399 x 257 ) / 102543
= 399 / 257
= 399
Step2:
LCM(1, 379) = 379
GCD(1, 379) = ( 1 x 379 ) / 379
= 1 / 379
= 1
Step3:
LCM(1, 371) = 371
GCD(1, 371) = ( 1 x 371 ) / 371
= 1 / 371
= 1
So, Greatest Common Divisor of 399, 257, 379, 371 is 1
