Product = 2 × 2 × 2 × 2 × 3 × 2 × 2 × 3 × 3 × 5 = 8640. This also works for the greatest common divisor (gcd), except that instead of multiplying all of the numbers in the Venn diagram, one multiplies only the prime factors that are in the intersection. Thus the gcd of 48 and 180 is 2 × 2 × 3 = 12.
LCM may refer to: Computing and mathematics. Latent class model, a concept in statistics; Least common multiple, a function of two integers; Living Computer Museum;
gcd(a, lcm(b, c)) = lcm(gcd(a, b), gcd(a, c)) lcm( a , gcd( b , c )) = gcd(lcm( a , b ), lcm( a , c )) . If we have the unique prime factorizations of a = p 1 e 1 p 2 e 2 ⋅⋅⋅ p m e m and b = p 1 f 1 p 2 f 2 ⋅⋅⋅ p m f m where e i ≥ 0 and f i ≥ 0 , then the GCD of a and b is
Then the matrix () having the greatest common divisor (,) as its entry is referred to as the GCD matrix on .The LCM matrix [] is defined analogously. [ 1 ] [ 2 ] The study of GCD type matrices originates from Smith (1875) who evaluated the determinant of certain GCD and LCM matrices.
In the 9th century, during Amoghavarsha's rule [1] Mahaviracharya wrote Ganitsara sangraha which is the first textbook on arithmetic in present day. [2] The book describes in details the current method of finding Lowest Common Multiple (LCM). [3]

Furthermore, if b 1, b 2 are both coprime with a, then so is their product b 1 b 2 (i.e., modulo a it is a product of invertible elements, and therefore invertible); [6] this also follows from the first point by Euclid's lemma, which states that if a prime number p divides a product bc, then p divides at least one of the factors b, c.
