Given numbers are 803, 968, 878, 990

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(803, 968) = 70664

GCD(803, 968) = ( 803 x 968 ) / 70664

= 803 / 968

= 803

Step2:

LCM(11, 878) = 9658

GCD(11, 878) = ( 11 x 878 ) / 9658

= 11 / 878

= 11

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 803, 968, 878, 990 is 1
