Given numbers are 253, 455, 963

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

Apply this formula for all numbers.

Step1:

LCM(253, 455) = 115115

GCD(253, 455) = ( 253 x 455 ) / 115115

= 253 / 455

= 253

Step2:

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

= 1 / 963

= 1

So, Greatest Common Divisor of 253, 455, 963 is 1
