Given numbers are 839, 290, 688, 278

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

Apply this formula for all numbers.

Step1:

LCM(839, 290) = 243310

GCD(839, 290) = ( 839 x 290 ) / 243310

= 839 / 290

= 839

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 278) = 278

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

= 1 / 278

= 1

So, Greatest Common Divisor of 839, 290, 688, 278 is 1
