Given numbers are 815, 491, 192, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 491) = 400165
GCD(815, 491) = ( 815 x 491 ) / 400165
= 815 / 491
= 815
Step2:
LCM(1, 192) = 192
GCD(1, 192) = ( 1 x 192 ) / 192
= 1 / 192
= 1
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 815, 491, 192, 515 is 1
