Given numbers are 689, 910, 129, 553

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

Apply this formula for all numbers.

Step1:

LCM(689, 910) = 48230

GCD(689, 910) = ( 689 x 910 ) / 48230

= 689 / 910

= 689

Step2:

LCM(13, 129) = 1677

GCD(13, 129) = ( 13 x 129 ) / 1677

= 13 / 129

= 13

Step3:

LCM(1, 553) = 553

GCD(1, 553) = ( 1 x 553 ) / 553

= 1 / 553

= 1

So, Greatest Common Divisor of 689, 910, 129, 553 is 1
