Given numbers are 103, 689, 295, 640

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

Apply this formula for all numbers.

Step1:

LCM(103, 689) = 70967

GCD(103, 689) = ( 103 x 689 ) / 70967

= 103 / 689

= 103

Step2:

LCM(1, 295) = 295

GCD(1, 295) = ( 1 x 295 ) / 295

= 1 / 295

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 103, 689, 295, 640 is 1
