Given numbers are 865, 990, 520, 942

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

Apply this formula for all numbers.

Step1:

LCM(865, 990) = 171270

GCD(865, 990) = ( 865 x 990 ) / 171270

= 865 / 990

= 865

Step2:

LCM(5, 520) = 520

GCD(5, 520) = ( 5 x 520 ) / 520

= 5 / 520

= 5

Step3:

LCM(5, 942) = 4710

GCD(5, 942) = ( 5 x 942 ) / 4710

= 5 / 942

= 5

So, Greatest Common Divisor of 865, 990, 520, 942 is 1
