Given numbers are 215, 165, 355, 115

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

Apply this formula for all numbers.

Step1:

LCM(215, 165) = 7095

GCD(215, 165) = ( 215 x 165 ) / 7095

= 215 / 165

= 215

Step2:

LCM(5, 355) = 355

GCD(5, 355) = ( 5 x 355 ) / 355

= 5 / 355

= 5

Step3:

LCM(5, 115) = 115

GCD(5, 115) = ( 5 x 115 ) / 115

= 5 / 115

= 5

So, Greatest Common Divisor of 215, 165, 355, 115 is 5
