Given numbers are 289, 820, 149, 652

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

Apply this formula for all numbers.

Step1:

LCM(289, 820) = 236980

GCD(289, 820) = ( 289 x 820 ) / 236980

= 289 / 820

= 289

Step2:

LCM(1, 149) = 149

GCD(1, 149) = ( 1 x 149 ) / 149

= 1 / 149

= 1

Step3:

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

= 1 / 652

= 1

So, Greatest Common Divisor of 289, 820, 149, 652 is 1
