Given numbers are 890, 905, 728, 135
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 905) = 161090
GCD(890, 905) = ( 890 x 905 ) / 161090
= 890 / 905
= 890
Step2:
LCM(5, 728) = 3640
GCD(5, 728) = ( 5 x 728 ) / 3640
= 5 / 728
= 5
Step3:
LCM(1, 135) = 135
GCD(1, 135) = ( 1 x 135 ) / 135
= 1 / 135
= 1
So, Greatest Common Divisor of 890, 905, 728, 135 is 1
