Given numbers are 689, 520, 821, 881

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

Apply this formula for all numbers.

Step1:

LCM(689, 520) = 27560

GCD(689, 520) = ( 689 x 520 ) / 27560

= 689 / 520

= 689

Step2:

LCM(13, 821) = 10673

GCD(13, 821) = ( 13 x 821 ) / 10673

= 13 / 821

= 13

Step3:

LCM(1, 881) = 881

GCD(1, 881) = ( 1 x 881 ) / 881

= 1 / 881

= 1

So, Greatest Common Divisor of 689, 520, 821, 881 is 1
