Given numbers are 261, 148, 280, 609

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

Apply this formula for all numbers.

Step1:

LCM(261, 148) = 38628

GCD(261, 148) = ( 261 x 148 ) / 38628

= 261 / 148

= 261

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 609) = 609

GCD(1, 609) = ( 1 x 609 ) / 609

= 1 / 609

= 1

So, Greatest Common Divisor of 261, 148, 280, 609 is 1
