Given numbers are 791, 538, 245, 258
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 538) = 425558
GCD(791, 538) = ( 791 x 538 ) / 425558
= 791 / 538
= 791
Step2:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
Step3:
LCM(1, 258) = 258
GCD(1, 258) = ( 1 x 258 ) / 258
= 1 / 258
= 1
So, Greatest Common Divisor of 791, 538, 245, 258 is 1
