Steps to Calculate GCD of 890, 305, 353, 805 using LCM Formula
Given numbers are 890, 305, 353, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(890, 305) = 54290
GCD(890, 305) = ( 890 x 305 ) / 54290
= 890 / 305
= 890
Step2:
LCM(5, 353) = 1765
GCD(5, 353) = ( 5 x 353 ) / 1765
= 5 / 353
= 5
Step3:
LCM(1, 805) = 805
GCD(1, 805) = ( 1 x 805 ) / 805
= 1 / 805
= 1
So, Greatest Common Divisor of 890, 305, 353, 805 is 1
