Given numbers are 826, 905, 827, 721
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(826, 905) = 747530
GCD(826, 905) = ( 826 x 905 ) / 747530
= 826 / 905
= 826
Step2:
LCM(1, 827) = 827
GCD(1, 827) = ( 1 x 827 ) / 827
= 1 / 827
= 1
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 826, 905, 827, 721 is 1
