Given numbers are 280, 772, 788, 775

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

Apply this formula for all numbers.

Step1:

LCM(280, 772) = 54040

GCD(280, 772) = ( 280 x 772 ) / 54040

= 280 / 772

= 280

Step2:

LCM(4, 788) = 788

GCD(4, 788) = ( 4 x 788 ) / 788

= 4 / 788

= 4

Step3:

LCM(4, 775) = 3100

GCD(4, 775) = ( 4 x 775 ) / 3100

= 4 / 775

= 4

So, Greatest Common Divisor of 280, 772, 788, 775 is 1
