If two terms in a binomial are perfect squares separated by subtraction, then you can factor them. Boost your career: Improve your Zoom skills. Since 20 x 1 = 20, 20 is a multiple of 20. https://www.mathsisfun.com/definitions/multiple.html, https://www.mathsisfun.com/least-common-multiple.html, https://www.khanacademy.org/math/pre-algebra/pre-algebra-factors-multiples/pre-algebra-lcm/v/least-common-multiple-exercise, https://www.youtube.com/watch?v=NKlOm3tPQiw, https://www.youtube.com/watch?v=b6qehkDuioQ, http://www.ducksters.com/kidsmath/division_basics.php, https://people.richland.edu/james/lecture/m116/polynomials/zeros.html, http://mathworld.wolfram.com/GreatestCommonDivisor.html, https://www.khanacademy.org/computing/computer-science/cryptography/modarithmetic/a/the-euclidean-algorithm, http://csharphelper.com/blog/2014/08/calculate-the-greatest-common-divisor-gcd-and-least-common-multiple-lcm-of-two-integers-in-c/, encontrar el mínimo común múltiplo de dos números, Encontrar o Mínimo Múltiplo Comum de Dois Números, Trovare il Minimo Comune Multiplo di Due Numeri, trouver le plus petit commun multiple de deux nombres, Kleinstes gemeinsames Vielfaches von zwei Zahlen berechnen, найти наименьшее общее кратное двух чисел, Het kleinste gemene veelvoud van twee getallen vinden, Mencari Kelipatan Persekutuan Terkecil dari Dua Angka, consider supporting our work with a contribution to wikiHow. Mila Zinkova. The formula is lcm(a, b) = a × b / gcd(a, b), where a and b are the numbers for which you want to find the LCM, and GCD is the greatest common divisor. Divide the GCF into either one of the 2 numbers, then multiply the result by the other number. Both 105 and 210 are factors of 630, therefore 630 is the least common multiple of the three numbers. You are right that the LCM is 2×3×3×5×7.

So, 630 is the least common multiple of 210 and 45. This image may not be used by other entities without the express written consent of wikiHow, Inc.
