Given numbers are 210, 289, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 289) = 60690
GCD(210, 289) = ( 210 x 289 ) / 60690
= 210 / 289
= 210
Step2:
LCM(1, 427) = 427
GCD(1, 427) = ( 1 x 427 ) / 427
= 1 / 427
= 1
So, Greatest Common Divisor of 210, 289, 427 is 1
