Given numbers are 280, 928, 788, 258

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

Apply this formula for all numbers.

Step1:

LCM(280, 928) = 32480

GCD(280, 928) = ( 280 x 928 ) / 32480

= 280 / 928

= 280

Step2:

LCM(8, 788) = 1576

GCD(8, 788) = ( 8 x 788 ) / 1576

= 8 / 788

= 8

Step3:

LCM(4, 258) = 516

GCD(4, 258) = ( 4 x 258 ) / 516

= 4 / 258

= 4

So, Greatest Common Divisor of 280, 928, 788, 258 is 2
