GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 207) = 84663
GCD(409, 207) = ( 409 x 207 ) / 84663
= 409 / 207
= 409
Step2:
LCM(1, 602) = 602
GCD(1, 602) = ( 1 x 602 ) / 602
= 1 / 602
= 1
Step3:
LCM(1, 168) = 168
GCD(1, 168) = ( 1 x 168 ) / 168
= 1 / 168
= 1
So, Greatest Common Divisor of 409, 207, 602, 168 is 1
