GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(815, 847) = 690305
GCD(815, 847) = ( 815 x 847 ) / 690305
= 815 / 847
= 815
Step2:
LCM(1, 472) = 472
GCD(1, 472) = ( 1 x 472 ) / 472
= 1 / 472
= 1
Step3:
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
= 1 / 777
= 1
So, Greatest Common Divisor of 815, 847, 472, 777 is 1
