Given numbers are 205, 785, 860, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 785) = 32185
GCD(205, 785) = ( 205 x 785 ) / 32185
= 205 / 785
= 205
Step2:
LCM(5, 860) = 860
GCD(5, 860) = ( 5 x 860 ) / 860
= 5 / 860
= 5
Step3:
LCM(5, 409) = 2045
GCD(5, 409) = ( 5 x 409 ) / 2045
= 5 / 409
= 5
So, Greatest Common Divisor of 205, 785, 860, 409 is 1
