Given numbers are 278, 310, 490, 995

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

Apply this formula for all numbers.

Step1:

LCM(278, 310) = 43090

GCD(278, 310) = ( 278 x 310 ) / 43090

= 278 / 310

= 278

Step2:

LCM(2, 490) = 490

GCD(2, 490) = ( 2 x 490 ) / 490

= 2 / 490

= 2

Step3:

LCM(2, 995) = 1990

GCD(2, 995) = ( 2 x 995 ) / 1990

= 2 / 995

= 2

So, Greatest Common Divisor of 278, 310, 490, 995 is 1
