Steps to Calculate GCD of 517, 391, 28, 265 using LCM Formula
Given numbers are 517, 391, 28, 265
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(517, 391) = 202147
GCD(517, 391) = ( 517 x 391 ) / 202147
= 517 / 391
= 517
Step2:
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
= 1 / 28
= 1
Step3:
LCM(1, 265) = 265
GCD(1, 265) = ( 1 x 265 ) / 265
= 1 / 265
= 1
So, Greatest Common Divisor of 517, 391, 28, 265 is 1
