Given numbers are 129, 160, 823, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 160) = 20640
GCD(129, 160) = ( 129 x 160 ) / 20640
= 129 / 160
= 129
Step2:
LCM(1, 823) = 823
GCD(1, 823) = ( 1 x 823 ) / 823
= 1 / 823
= 1
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 129, 160, 823, 780 is 1
