Given numbers are 280, 861, 961, 244

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

Apply this formula for all numbers.

Step1:

LCM(280, 861) = 34440

GCD(280, 861) = ( 280 x 861 ) / 34440

= 280 / 861

= 280

Step2:

LCM(7, 961) = 6727

GCD(7, 961) = ( 7 x 961 ) / 6727

= 7 / 961

= 7

Step3:

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

= 1 / 244

= 1

So, Greatest Common Divisor of 280, 861, 961, 244 is 1
