1º factorize (descompones en factores primos) 140 : 2 325 : 5 490 : 2 70 : 2 65 : 5 245 : 5 35 : 5 13 : 13 49 : 7 7 : 7 1 7 : 7 1 1
140 = 2² * 5 * 7
325 = 5² * 13
490 = 2 * 5 * 7² - Take the common factors with smaller or lesserexponent (only 5 is common) Tomas los factores comunes a los 3 númeroscon menor exponente.
M. c.
D (140, 325, 490) = 5.
