GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(998, 680) = 339320
GCD(998, 680) = ( 998 x 680 ) / 339320
= 998 / 680
= 998
Step2:
LCM(2, 259) = 518
GCD(2, 259) = ( 2 x 259 ) / 518
= 2 / 259
= 2
Step3:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
So, Greatest Common Divisor of 998, 680, 259, 138 is 1
