Given numbers are 718, 448, 643, 209
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(718, 448) = 160832
GCD(718, 448) = ( 718 x 448 ) / 160832
= 718 / 448
= 718
Step2:
LCM(2, 643) = 1286
GCD(2, 643) = ( 2 x 643 ) / 1286
= 2 / 643
= 2
Step3:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
So, Greatest Common Divisor of 718, 448, 643, 209 is 1
