Given numbers are 640, 248, 349, 568

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

Apply this formula for all numbers.

Step1:

LCM(640, 248) = 19840

GCD(640, 248) = ( 640 x 248 ) / 19840

= 640 / 248

= 640

Step2:

LCM(8, 349) = 2792

GCD(8, 349) = ( 8 x 349 ) / 2792

= 8 / 349

= 8

Step3:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

So, Greatest Common Divisor of 640, 248, 349, 568 is 1
