Given numbers are 255, 753, 617, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 753) = 64005
GCD(255, 753) = ( 255 x 753 ) / 64005
= 255 / 753
= 255
Step2:
LCM(3, 617) = 1851
GCD(3, 617) = ( 3 x 617 ) / 1851
= 3 / 617
= 3
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 255, 753, 617, 447 is 1
