Given numbers are 791, 981, 559, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 981) = 775971
GCD(791, 981) = ( 791 x 981 ) / 775971
= 791 / 981
= 791
Step2:
LCM(1, 559) = 559
GCD(1, 559) = ( 1 x 559 ) / 559
= 1 / 559
= 1
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 791, 981, 559, 245 is 1
