Given numbers are 860, 385, 630, 455

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

Apply this formula for all numbers.

Step1:

LCM(860, 385) = 66220

GCD(860, 385) = ( 860 x 385 ) / 66220

= 860 / 385

= 860

Step2:

LCM(5, 630) = 630

GCD(5, 630) = ( 5 x 630 ) / 630

= 5 / 630

= 5

Step3:

LCM(5, 455) = 455

GCD(5, 455) = ( 5 x 455 ) / 455

= 5 / 455

= 5

So, Greatest Common Divisor of 860, 385, 630, 455 is 5
