Given numbers are 791, 987, 163, 518
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 987) = 111531
GCD(791, 987) = ( 791 x 987 ) / 111531
= 791 / 987
= 791
Step2:
LCM(7, 163) = 1141
GCD(7, 163) = ( 7 x 163 ) / 1141
= 7 / 163
= 7
Step3:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
So, Greatest Common Divisor of 791, 987, 163, 518 is 1
