Given numbers are 402, 269, 209, 669
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 269) = 108138
GCD(402, 269) = ( 402 x 269 ) / 108138
= 402 / 269
= 402
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
So, Greatest Common Divisor of 402, 269, 209, 669 is 1
