Given numbers are 819, 905, 245, 251
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 905) = 741195
GCD(819, 905) = ( 819 x 905 ) / 741195
= 819 / 905
= 819
Step2:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
Step3:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
So, Greatest Common Divisor of 819, 905, 245, 251 is 1
