Given numbers are 665, 866, 281, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 866) = 575890
GCD(665, 866) = ( 665 x 866 ) / 575890
= 665 / 866
= 665
Step2:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 665, 866, 281, 813 is 1
