GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(343, 688) = 235984
GCD(343, 688) = ( 343 x 688 ) / 235984
= 343 / 688
= 343
Step2:
LCM(1, 555) = 555
GCD(1, 555) = ( 1 x 555 ) / 555
= 1 / 555
= 1
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 343, 688, 555, 665 is 1
