Given numbers are 689, 513, 125, 626

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

Apply this formula for all numbers.

Step1:

LCM(689, 513) = 353457

GCD(689, 513) = ( 689 x 513 ) / 353457

= 689 / 513

= 689

Step2:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

Step3:

LCM(1, 626) = 626

GCD(1, 626) = ( 1 x 626 ) / 626

= 1 / 626

= 1

So, Greatest Common Divisor of 689, 513, 125, 626 is 1
