GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 646) = 215764
GCD(668, 646) = ( 668 x 646 ) / 215764
= 668 / 646
= 668
Step2:
LCM(2, 340) = 340
GCD(2, 340) = ( 2 x 340 ) / 340
= 2 / 340
= 2
Step3:
LCM(2, 259) = 518
GCD(2, 259) = ( 2 x 259 ) / 518
= 2 / 259
= 2
So, Greatest Common Divisor of 668, 646, 340, 259 is 1
