Given numbers are 839, 293, 645, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(839, 293) = 245827
GCD(839, 293) = ( 839 x 293 ) / 245827
= 839 / 293
= 839
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 839, 293, 645, 257 is 1
