Given numbers are 805, 278, 989, 531

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

Apply this formula for all numbers.

Step1:

LCM(805, 278) = 223790

GCD(805, 278) = ( 805 x 278 ) / 223790

= 805 / 278

= 805

Step2:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

Step3:

LCM(1, 531) = 531

GCD(1, 531) = ( 1 x 531 ) / 531

= 1 / 531

= 1

So, Greatest Common Divisor of 805, 278, 989, 531 is 1
