GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(613, 882) = 540666
GCD(613, 882) = ( 613 x 882 ) / 540666
= 613 / 882
= 613
Step2:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 613, 882, 991, 390 is 1
