Given numbers are 813, 392, 493, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 392) = 318696
GCD(813, 392) = ( 813 x 392 ) / 318696
= 813 / 392
= 813
Step2:
LCM(1, 493) = 493
GCD(1, 493) = ( 1 x 493 ) / 493
= 1 / 493
= 1
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 813, 392, 493, 278 is 1
