Given numbers are 687, 195, 37, 278

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

Apply this formula for all numbers.

Step1:

LCM(687, 195) = 44655

GCD(687, 195) = ( 687 x 195 ) / 44655

= 687 / 195

= 687

Step2:

LCM(3, 37) = 111

GCD(3, 37) = ( 3 x 37 ) / 111

= 3 / 37

= 3

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 687, 195, 37, 278 is 1
