Given numbers are 689, 526, 758, 278

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

Apply this formula for all numbers.

Step1:

LCM(689, 526) = 362414

GCD(689, 526) = ( 689 x 526 ) / 362414

= 689 / 526

= 689

Step2:

LCM(1, 758) = 758

GCD(1, 758) = ( 1 x 758 ) / 758

= 1 / 758

= 1

Step3:

LCM(1, 278) = 278

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

= 1 / 278

= 1

So, Greatest Common Divisor of 689, 526, 758, 278 is 1
