Given numbers are 862, 238, 779, 781

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

Apply this formula for all numbers.

Step1:

LCM(862, 238) = 102578

GCD(862, 238) = ( 862 x 238 ) / 102578

= 862 / 238

= 862

Step2:

LCM(2, 779) = 1558

GCD(2, 779) = ( 2 x 779 ) / 1558

= 2 / 779

= 2

Step3:

LCM(1, 781) = 781

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

= 1 / 781

= 1

So, Greatest Common Divisor of 862, 238, 779, 781 is 1
