Given numbers are 385, 310, 817, 697
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 310) = 23870
GCD(385, 310) = ( 385 x 310 ) / 23870
= 385 / 310
= 385
Step2:
LCM(5, 817) = 4085
GCD(5, 817) = ( 5 x 817 ) / 4085
= 5 / 817
= 5
Step3:
LCM(1, 697) = 697
GCD(1, 697) = ( 1 x 697 ) / 697
= 1 / 697
= 1
So, Greatest Common Divisor of 385, 310, 817, 697 is 1
