GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 778) = 154822
GCD(398, 778) = ( 398 x 778 ) / 154822
= 398 / 778
= 398
Step2:
LCM(2, 909) = 1818
GCD(2, 909) = ( 2 x 909 ) / 1818
= 2 / 909
= 2
Step3:
LCM(1, 444) = 444
GCD(1, 444) = ( 1 x 444 ) / 444
= 1 / 444
= 1
So, Greatest Common Divisor of 398, 778, 909, 444 is 1
