Given numbers are 129, 448, 343, 878
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 448) = 57792
GCD(129, 448) = ( 129 x 448 ) / 57792
= 129 / 448
= 129
Step2:
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
= 1 / 343
= 1
Step3:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
So, Greatest Common Divisor of 129, 448, 343, 878 is 1
