Given numbers are 280, 472, 61, 969

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

Apply this formula for all numbers.

Step1:

LCM(280, 472) = 16520

GCD(280, 472) = ( 280 x 472 ) / 16520

= 280 / 472

= 280

Step2:

LCM(8, 61) = 488

GCD(8, 61) = ( 8 x 61 ) / 488

= 8 / 61

= 8

Step3:

LCM(1, 969) = 969

GCD(1, 969) = ( 1 x 969 ) / 969

= 1 / 969

= 1

So, Greatest Common Divisor of 280, 472, 61, 969 is 1
