Given numbers are 345, 485, 815, 103
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 485) = 33465
GCD(345, 485) = ( 345 x 485 ) / 33465
= 345 / 485
= 345
Step2:
LCM(5, 815) = 815
GCD(5, 815) = ( 5 x 815 ) / 815
= 5 / 815
= 5
Step3:
LCM(5, 103) = 515
GCD(5, 103) = ( 5 x 103 ) / 515
= 5 / 103
= 5
So, Greatest Common Divisor of 345, 485, 815, 103 is 1
