Given numbers are 686, 850, 335, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 850) = 291550
GCD(686, 850) = ( 686 x 850 ) / 291550
= 686 / 850
= 686
Step2:
LCM(2, 335) = 670
GCD(2, 335) = ( 2 x 335 ) / 670
= 2 / 335
= 2
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 686, 850, 335, 409 is 1
