Steps to Calculate GCD of 105, 389, 783, 775 using LCM Formula
Given numbers are 105, 389, 783, 775
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 389) = 40845
GCD(105, 389) = ( 105 x 389 ) / 40845
= 105 / 389
= 105
Step2:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
Step3:
LCM(1, 775) = 775
GCD(1, 775) = ( 1 x 775 ) / 775
= 1 / 775
= 1
So, Greatest Common Divisor of 105, 389, 783, 775 is 1
