Given numbers are 705, 260, 115, 145

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

Apply this formula for all numbers.

Step1:

LCM(705, 260) = 36660

GCD(705, 260) = ( 705 x 260 ) / 36660

= 705 / 260

= 705

Step2:

LCM(5, 115) = 115

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

= 5 / 115

= 5

Step3:

LCM(5, 145) = 145

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

= 5 / 145

= 5

So, Greatest Common Divisor of 705, 260, 115, 145 is 5
