GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 543) = 72219
GCD(399, 543) = ( 399 x 543 ) / 72219
= 399 / 543
= 399
Step2:
LCM(3, 775) = 2325
GCD(3, 775) = ( 3 x 775 ) / 2325
= 3 / 775
= 3
Step3:
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
= 1 / 777
= 1
So, Greatest Common Divisor of 399, 543, 775, 777 is 1
