Given numbers are 810, 980, 317, 238
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 980) = 79380
GCD(810, 980) = ( 810 x 980 ) / 79380
= 810 / 980
= 810
Step2:
LCM(10, 317) = 3170
GCD(10, 317) = ( 10 x 317 ) / 3170
= 10 / 317
= 10
Step3:
LCM(1, 238) = 238
GCD(1, 238) = ( 1 x 238 ) / 238
= 1 / 238
= 1
So, Greatest Common Divisor of 810, 980, 317, 238 is 1
