3 x 3 x 3 x 7 x 7 = 1323The factors of 1323 are 1, 3, 7, 9, 21, 27, 49, 63, 147, 189, 441, 1323
This isn't a great example, because the powers (exponents) of these two numbers are equal. 22 x 5 = 20 22 x 7 = 28 The GCF is 22 which is 4.
105 times the factor that seems to have been missed out before "... and 7". And all multiples of the result.
Ex: 3/a + 4/b = 7, LCD is ab ab x (3/a) + ab x (4/b) = ab x 7 3b + 4a = 7ab so that the denominators have cancelled. a and b can represent binomials, monomials, polynomials, etc. EX: 3/(x+2) + 4/(x-5) = 7 multiply by ab = (x+2)(x-5)
2 x 3 x 3 x 7 x 7 = 882 2 x 2 x 2 x 3 x 7 x 7 x 7 = 8232 2 x 2 x 2 x 3 x 3 x 7 x 7 x 7 = 24696, the LCM
