Given numbers are 405, 925, 206, 810
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 925) = 74925
GCD(405, 925) = ( 405 x 925 ) / 74925
= 405 / 925
= 405
Step2:
LCM(5, 206) = 1030
GCD(5, 206) = ( 5 x 206 ) / 1030
= 5 / 206
= 5
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 405, 925, 206, 810 is 1
