Given numbers are 669, 666, 494, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(669, 666) = 148518
GCD(669, 666) = ( 669 x 666 ) / 148518
= 669 / 666
= 669
Step2:
LCM(3, 494) = 1482
GCD(3, 494) = ( 3 x 494 ) / 1482
= 3 / 494
= 3
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 669, 666, 494, 685 is 1
