Given numbers are 689, 146, 278, 192

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

Apply this formula for all numbers.

Step1:

LCM(689, 146) = 100594

GCD(689, 146) = ( 689 x 146 ) / 100594

= 689 / 146

= 689

Step2:

LCM(1, 278) = 278

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

= 1 / 278

= 1

Step3:

LCM(1, 192) = 192

GCD(1, 192) = ( 1 x 192 ) / 192

= 1 / 192

= 1

So, Greatest Common Divisor of 689, 146, 278, 192 is 1
