GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 853) = 210691
GCD(247, 853) = ( 247 x 853 ) / 210691
= 247 / 853
= 247
Step2:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 247, 853, 387, 439 is 1
