Given numbers are 304, 437, 721, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(304, 437) = 6992
GCD(304, 437) = ( 304 x 437 ) / 6992
= 304 / 437
= 304
Step2:
LCM(19, 721) = 13699
GCD(19, 721) = ( 19 x 721 ) / 13699
= 19 / 721
= 19
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 304, 437, 721, 643 is 1
