Given numbers are 206, 120, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 120) = 12360
GCD(206, 120) = ( 206 x 120 ) / 12360
= 206 / 120
= 206
Step2:
LCM(2, 257) = 514
GCD(2, 257) = ( 2 x 257 ) / 514
= 2 / 257
= 2
So, Greatest Common Divisor of 206, 120, 257 is 1
