Given numbers are 842, 664, 727, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 664) = 279544
GCD(842, 664) = ( 842 x 664 ) / 279544
= 842 / 664
= 842
Step2:
LCM(2, 727) = 1454
GCD(2, 727) = ( 2 x 727 ) / 1454
= 2 / 727
= 2
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 842, 664, 727, 405 is 1
