Steps to Calculate GCD of 731, 257, 133, 765 using LCM Formula
Given numbers are 731, 257, 133, 765
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(731, 257) = 187867
GCD(731, 257) = ( 731 x 257 ) / 187867
= 731 / 257
= 731
Step2:
LCM(1, 133) = 133
GCD(1, 133) = ( 1 x 133 ) / 133
= 1 / 133
= 1
Step3:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
So, Greatest Common Divisor of 731, 257, 133, 765 is 1
