Given numbers are 978, 986, 151, 781

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

Apply this formula for all numbers.

Step1:

LCM(978, 986) = 482154

GCD(978, 986) = ( 978 x 986 ) / 482154

= 978 / 986

= 978

Step2:

LCM(2, 151) = 302

GCD(2, 151) = ( 2 x 151 ) / 302

= 2 / 151

= 2

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 978, 986, 151, 781 is 1
