Given numbers are 345, 648, 771, 775
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 648) = 74520
GCD(345, 648) = ( 345 x 648 ) / 74520
= 345 / 648
= 345
Step2:
LCM(3, 771) = 771
GCD(3, 771) = ( 3 x 771 ) / 771
= 3 / 771
= 3
Step3:
LCM(3, 775) = 2325
GCD(3, 775) = ( 3 x 775 ) / 2325
= 3 / 775
= 3
So, Greatest Common Divisor of 345, 648, 771, 775 is 1
