Given numbers are 568, 164, 166, 781

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

Apply this formula for all numbers.

Step1:

LCM(568, 164) = 23288

GCD(568, 164) = ( 568 x 164 ) / 23288

= 568 / 164

= 568

Step2:

LCM(4, 166) = 332

GCD(4, 166) = ( 4 x 166 ) / 332

= 4 / 166

= 4

Step3:

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

= 2 / 781

= 2

So, Greatest Common Divisor of 568, 164, 166, 781 is 1
