Given numbers are 517, 391, 204, 472
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, 204) = 204
GCD(1, 204) = ( 1 x 204 ) / 204
= 1 / 204
= 1
Step3:
LCM(1, 472) = 472
GCD(1, 472) = ( 1 x 472 ) / 472
= 1 / 472
= 1
So, Greatest Common Divisor of 517, 391, 204, 472 is 1
