Given numbers are 780, 949, 217, 872
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 949) = 56940
GCD(780, 949) = ( 780 x 949 ) / 56940
= 780 / 949
= 780
Step2:
LCM(13, 217) = 2821
GCD(13, 217) = ( 13 x 217 ) / 2821
= 13 / 217
= 13
Step3:
LCM(1, 872) = 872
GCD(1, 872) = ( 1 x 872 ) / 872
= 1 / 872
= 1
So, Greatest Common Divisor of 780, 949, 217, 872 is 1
