Given numbers are 815, 138, 409, 673
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 138) = 112470
GCD(815, 138) = ( 815 x 138 ) / 112470
= 815 / 138
= 815
Step2:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
Step3:
LCM(1, 673) = 673
GCD(1, 673) = ( 1 x 673 ) / 673
= 1 / 673
= 1
So, Greatest Common Divisor of 815, 138, 409, 673 is 1
