Given numbers are 813, 431, 15, 537
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 431) = 350403
GCD(813, 431) = ( 813 x 431 ) / 350403
= 813 / 431
= 813
Step2:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
Step3:
LCM(1, 537) = 537
GCD(1, 537) = ( 1 x 537 ) / 537
= 1 / 537
= 1
So, Greatest Common Divisor of 813, 431, 15, 537 is 1
