Given numbers are 865, 895, 145, 991

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

Apply this formula for all numbers.

Step1:

LCM(865, 895) = 154835

GCD(865, 895) = ( 865 x 895 ) / 154835

= 865 / 895

= 865

Step2:

LCM(5, 145) = 145

GCD(5, 145) = ( 5 x 145 ) / 145

= 5 / 145

= 5

Step3:

LCM(5, 991) = 4955

GCD(5, 991) = ( 5 x 991 ) / 4955

= 5 / 991

= 5

So, Greatest Common Divisor of 865, 895, 145, 991 is 1
