Given numbers are 813, 781, 103, 582
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 781) = 634953
GCD(813, 781) = ( 813 x 781 ) / 634953
= 813 / 781
= 813
Step2:
LCM(1, 103) = 103
GCD(1, 103) = ( 1 x 103 ) / 103
= 1 / 103
= 1
Step3:
LCM(1, 582) = 582
GCD(1, 582) = ( 1 x 582 ) / 582
= 1 / 582
= 1
So, Greatest Common Divisor of 813, 781, 103, 582 is 1
