Given numbers are 805, 620, 431, 897
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 620) = 99820
GCD(805, 620) = ( 805 x 620 ) / 99820
= 805 / 620
= 805
Step2:
LCM(5, 431) = 2155
GCD(5, 431) = ( 5 x 431 ) / 2155
= 5 / 431
= 5
Step3:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
So, Greatest Common Divisor of 805, 620, 431, 897 is 1
