Given numbers are 255, 295, 787, 972

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

Apply this formula for all numbers.

Step1:

LCM(255, 295) = 15045

GCD(255, 295) = ( 255 x 295 ) / 15045

= 255 / 295

= 255

Step2:

LCM(5, 787) = 3935

GCD(5, 787) = ( 5 x 787 ) / 3935

= 5 / 787

= 5

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 255, 295, 787, 972 is 1
