Given numbers are 905, 564, 915, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 564) = 510420
GCD(905, 564) = ( 905 x 564 ) / 510420
= 905 / 564
= 905
Step2:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 905, 564, 915, 721 is 1
