GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 657) = 27594
GCD(378, 657) = ( 378 x 657 ) / 27594
= 378 / 657
= 378
Step2:
LCM(9, 449) = 4041
GCD(9, 449) = ( 9 x 449 ) / 4041
= 9 / 449
= 9
Step3:
LCM(1, 868) = 868
GCD(1, 868) = ( 1 x 868 ) / 868
= 1 / 868
= 1
So, Greatest Common Divisor of 378, 657, 449, 868 is 1
