Given numbers are 447, 779, 855, 219
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 779) = 348213
GCD(447, 779) = ( 447 x 779 ) / 348213
= 447 / 779
= 447
Step2:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
Step3:
LCM(1, 219) = 219
GCD(1, 219) = ( 1 x 219 ) / 219
= 1 / 219
= 1
So, Greatest Common Divisor of 447, 779, 855, 219 is 1
