Given numbers are 175, 665, 120, 855

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

Apply this formula for all numbers.

Step1:

LCM(175, 665) = 3325

GCD(175, 665) = ( 175 x 665 ) / 3325

= 175 / 665

= 175

Step2:

LCM(35, 120) = 840

GCD(35, 120) = ( 35 x 120 ) / 840

= 35 / 120

= 35

Step3:

LCM(5, 855) = 855

GCD(5, 855) = ( 5 x 855 ) / 855

= 5 / 855

= 5

So, Greatest Common Divisor of 175, 665, 120, 855 is 5
