Given numbers are 871, 321, 751, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(871, 321) = 279591
GCD(871, 321) = ( 871 x 321 ) / 279591
= 871 / 321
= 871
Step2:
LCM(1, 751) = 751
GCD(1, 751) = ( 1 x 751 ) / 751
= 1 / 751
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 871, 321, 751, 643 is 1
