Given numbers are 618, 771, 310, 449
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 771) = 158826
GCD(618, 771) = ( 618 x 771 ) / 158826
= 618 / 771
= 618
Step2:
LCM(3, 310) = 930
GCD(3, 310) = ( 3 x 310 ) / 930
= 3 / 310
= 3
Step3:
LCM(1, 449) = 449
GCD(1, 449) = ( 1 x 449 ) / 449
= 1 / 449
= 1
So, Greatest Common Divisor of 618, 771, 310, 449 is 1
