Given numbers are 285, 865, 955, 778

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

Apply this formula for all numbers.

Step1:

LCM(285, 865) = 49305

GCD(285, 865) = ( 285 x 865 ) / 49305

= 285 / 865

= 285

Step2:

LCM(5, 955) = 955

GCD(5, 955) = ( 5 x 955 ) / 955

= 5 / 955

= 5

Step3:

LCM(5, 778) = 3890

GCD(5, 778) = ( 5 x 778 ) / 3890

= 5 / 778

= 5

So, Greatest Common Divisor of 285, 865, 955, 778 is 1
