Given numbers are 123, 478, 408, 669
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 478) = 58794
GCD(123, 478) = ( 123 x 478 ) / 58794
= 123 / 478
= 123
Step2:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
Step3:
LCM(1, 669) = 669
GCD(1, 669) = ( 1 x 669 ) / 669
= 1 / 669
= 1
So, Greatest Common Divisor of 123, 478, 408, 669 is 1
