Given numbers are 855, 839, 293, 451
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 839) = 717345
GCD(855, 839) = ( 855 x 839 ) / 717345
= 855 / 839
= 855
Step2:
LCM(1, 293) = 293
GCD(1, 293) = ( 1 x 293 ) / 293
= 1 / 293
= 1
Step3:
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
= 1 / 451
= 1
So, Greatest Common Divisor of 855, 839, 293, 451 is 1
