Given numbers are 206, 978, 259, 202
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 978) = 100734
GCD(206, 978) = ( 206 x 978 ) / 100734
= 206 / 978
= 206
Step2:
LCM(2, 259) = 518
GCD(2, 259) = ( 2 x 259 ) / 518
= 2 / 259
= 2
Step3:
LCM(1, 202) = 202
GCD(1, 202) = ( 1 x 202 ) / 202
= 1 / 202
= 1
So, Greatest Common Divisor of 206, 978, 259, 202 is 1
