## LEAST COMMON MULTIPLE: LCM(40, 56) (PRIME FACTORS METHOD) RESULT

LCM(40, 56) = 280 DESCRIPTIONS

Prime factorization of 40 :

(40 = 2 × 2 × 2 × 5)

Prime factorization of 56 :

(56 = 2 × 2 × 2 × 7)

• 40 = 2 × 2 × 2 × 5
• 56 = 2 × 2 × 2 × 7

Provided that the common prime factors (2, 2 and 2) appear in the multiplication only once, the LCM of 40 and 56 is equal to the product of all prime factors.

LCM(40, 56) = 2 × 2 × 2 × 5 × 7 = 280
