Given numbers are 285, 645, 412, 965

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

Apply this formula for all numbers.

Step1:

LCM(285, 645) = 12255

GCD(285, 645) = ( 285 x 645 ) / 12255

= 285 / 645

= 285

Step2:

LCM(15, 412) = 6180

GCD(15, 412) = ( 15 x 412 ) / 6180

= 15 / 412

= 15

Step3:

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

= 1 / 965

= 1

So, Greatest Common Divisor of 285, 645, 412, 965 is 1
