Given numbers are 643, 856, 301, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 856) = 550408
GCD(643, 856) = ( 643 x 856 ) / 550408
= 643 / 856
= 643
Step2:
LCM(1, 301) = 301
GCD(1, 301) = ( 1 x 301 ) / 301
= 1 / 301
= 1
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 643, 856, 301, 905 is 1
