Given numbers are 105, 221, 798, 725
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 221) = 23205
GCD(105, 221) = ( 105 x 221 ) / 23205
= 105 / 221
= 105
Step2:
LCM(1, 798) = 798
GCD(1, 798) = ( 1 x 798 ) / 798
= 1 / 798
= 1
Step3:
LCM(1, 725) = 725
GCD(1, 725) = ( 1 x 725 ) / 725
= 1 / 725
= 1
So, Greatest Common Divisor of 105, 221, 798, 725 is 1
