Given numbers are 980, 448, 781, 979

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

Apply this formula for all numbers.

Step1:

LCM(980, 448) = 15680

GCD(980, 448) = ( 980 x 448 ) / 15680

= 980 / 448

= 980

Step2:

LCM(28, 781) = 21868

GCD(28, 781) = ( 28 x 781 ) / 21868

= 28 / 781

= 28

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 980, 448, 781, 979 is 1
