GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 988) = 12844
GCD(169, 988) = ( 169 x 988 ) / 12844
= 169 / 988
= 169
Step2:
LCM(13, 654) = 8502
GCD(13, 654) = ( 13 x 654 ) / 8502
= 13 / 654
= 13
Step3:
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
= 1 / 343
= 1
So, Greatest Common Divisor of 169, 988, 654, 343 is 1
