Given numbers are 690, 806, 898, 549

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

Apply this formula for all numbers.

Step1:

LCM(690, 806) = 278070

GCD(690, 806) = ( 690 x 806 ) / 278070

= 690 / 806

= 690

Step2:

LCM(2, 898) = 898

GCD(2, 898) = ( 2 x 898 ) / 898

= 2 / 898

= 2

Step3:

LCM(2, 549) = 1098

GCD(2, 549) = ( 2 x 549 ) / 1098

= 2 / 549

= 2

So, Greatest Common Divisor of 690, 806, 898, 549 is 1
