Given numbers are 120, 865, 425, 670

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

Apply this formula for all numbers.

Step1:

LCM(120, 865) = 20760

GCD(120, 865) = ( 120 x 865 ) / 20760

= 120 / 865

= 120

Step2:

LCM(5, 425) = 425

GCD(5, 425) = ( 5 x 425 ) / 425

= 5 / 425

= 5

Step3:

LCM(5, 670) = 670

GCD(5, 670) = ( 5 x 670 ) / 670

= 5 / 670

= 5

So, Greatest Common Divisor of 120, 865, 425, 670 is 5
