Given numbers are 406, 981, 551, 781

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

Apply this formula for all numbers.

Step1:

LCM(406, 981) = 398286

GCD(406, 981) = ( 406 x 981 ) / 398286

= 406 / 981

= 406

Step2:

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

= 1 / 551

= 1

Step3:

LCM(1, 781) = 781

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

= 1 / 781

= 1

So, Greatest Common Divisor of 406, 981, 551, 781 is 1
