Given numbers are 381, 782, 396, 857
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 782) = 297942
GCD(381, 782) = ( 381 x 782 ) / 297942
= 381 / 782
= 381
Step2:
LCM(1, 396) = 396
GCD(1, 396) = ( 1 x 396 ) / 396
= 1 / 396
= 1
Step3:
LCM(1, 857) = 857
GCD(1, 857) = ( 1 x 857 ) / 857
= 1 / 857
= 1
So, Greatest Common Divisor of 381, 782, 396, 857 is 1
