GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(323, 162) = 52326
GCD(323, 162) = ( 323 x 162 ) / 52326
= 323 / 162
= 323
Step2:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 323, 162, 978, 147 is 1
