Given numbers are 424, 112, 781, 978

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

Apply this formula for all numbers.

Step1:

LCM(424, 112) = 5936

GCD(424, 112) = ( 424 x 112 ) / 5936

= 424 / 112

= 424

Step2:

LCM(8, 781) = 6248

GCD(8, 781) = ( 8 x 781 ) / 6248

= 8 / 781

= 8

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 424, 112, 781, 978 is 1
