Given numbers are 865, 365, 370, 218

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 365 are 5 x 73

Prime factors of 370 are 2 x 5 x 37

Prime factors of 218 are 2 x 109

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 865, 365, 370, 218

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

Apply this formula for all numbers.

Step1:

LCM(865, 365) = 63145

GCD(865, 365) = ( 865 x 365 ) / 63145

= 865 / 365

= 865

Step2:

LCM(5, 370) = 370

GCD(5, 370) = ( 5 x 370 ) / 370

= 5 / 370

= 5

Step3:

LCM(5, 218) = 1090

GCD(5, 218) = ( 5 x 218 ) / 1090

= 5 / 218

= 5

So, Greatest Common Divisor of 865, 365, 370, 218 is 1
