Given numbers are 448, 399, 846, 720
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(448, 399) = 25536
GCD(448, 399) = ( 448 x 399 ) / 25536
= 448 / 399
= 448
Step2:
LCM(7, 846) = 5922
GCD(7, 846) = ( 7 x 846 ) / 5922
= 7 / 846
= 7
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 448, 399, 846, 720 is 1
