Given numbers are 689, 814, 906, 769

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

Apply this formula for all numbers.

Step1:

LCM(689, 814) = 560846

GCD(689, 814) = ( 689 x 814 ) / 560846

= 689 / 814

= 689

Step2:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

Step3:

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

= 1 / 769

= 1

So, Greatest Common Divisor of 689, 814, 906, 769 is 1
