Given numbers are 255, 751, 20
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 751) = 191505
GCD(255, 751) = ( 255 x 751 ) / 191505
= 255 / 751
= 255
Step2:
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
= 1 / 20
= 1
So, Greatest Common Divisor of 255, 751, 20 is 1
