Given numbers are 720, 164, 156, 819
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 164) = 29520
GCD(720, 164) = ( 720 x 164 ) / 29520
= 720 / 164
= 720
Step2:
LCM(4, 156) = 156
GCD(4, 156) = ( 4 x 156 ) / 156
= 4 / 156
= 4
Step3:
LCM(4, 819) = 3276
GCD(4, 819) = ( 4 x 819 ) / 3276
= 4 / 819
= 4
So, Greatest Common Divisor of 720, 164, 156, 819 is 1
