Given numbers are 672, 678, 682, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 678) = 75936
GCD(672, 678) = ( 672 x 678 ) / 75936
= 672 / 678
= 672
Step2:
LCM(6, 682) = 2046
GCD(6, 682) = ( 6 x 682 ) / 2046
= 6 / 682
= 6
Step3:
LCM(2, 405) = 810
GCD(2, 405) = ( 2 x 405 ) / 810
= 2 / 405
= 2
So, Greatest Common Divisor of 672, 678, 682, 405 is 1
