Given numbers are 819, 140, 383, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 140) = 16380
GCD(819, 140) = ( 819 x 140 ) / 16380
= 819 / 140
= 819
Step2:
LCM(7, 383) = 2681
GCD(7, 383) = ( 7 x 383 ) / 2681
= 7 / 383
= 7
Step3:
LCM(1, 665) = 665
GCD(1, 665) = ( 1 x 665 ) / 665
= 1 / 665
= 1
So, Greatest Common Divisor of 819, 140, 383, 665 is 1
