Given numbers are 255, 735, 402, 456

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

Apply this formula for all numbers.

Step1:

LCM(255, 735) = 12495

GCD(255, 735) = ( 255 x 735 ) / 12495

= 255 / 735

= 255

Step2:

LCM(15, 402) = 2010

GCD(15, 402) = ( 15 x 402 ) / 2010

= 15 / 402

= 15

Step3:

LCM(3, 456) = 456

GCD(3, 456) = ( 3 x 456 ) / 456

= 3 / 456

= 3

So, Greatest Common Divisor of 255, 735, 402, 456 is 3
