GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 777) = 43512
GCD(392, 777) = ( 392 x 777 ) / 43512
= 392 / 777
= 392
Step2:
LCM(7, 997) = 6979
GCD(7, 997) = ( 7 x 997 ) / 6979
= 7 / 997
= 7
Step3:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 392, 777, 997, 145 is 1
