GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 399) = 90174
GCD(678, 399) = ( 678 x 399 ) / 90174
= 678 / 399
= 678
Step2:
LCM(3, 185) = 555
GCD(3, 185) = ( 3 x 185 ) / 555
= 3 / 185
= 3
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 678, 399, 185, 847 is 1
