Given numbers are 643, 349, 851, 788
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 349) = 224407
GCD(643, 349) = ( 643 x 349 ) / 224407
= 643 / 349
= 643
Step2:
LCM(1, 851) = 851
GCD(1, 851) = ( 1 x 851 ) / 851
= 1 / 851
= 1
Step3:
LCM(1, 788) = 788
GCD(1, 788) = ( 1 x 788 ) / 788
= 1 / 788
= 1
So, Greatest Common Divisor of 643, 349, 851, 788 is 1
