Least Common Multiple (LCM) for 40 70 is 280The Least Common Multiple (LCM) is the smallest number that two or more numbers will divide into evenly. NOTE: to find LCM you first need to know how to find GCD/GCF.Step 1: Find the GCF (Greatest Common Factor ) of 40 and 70 which is 10Step 2: Multiply the numbers 40 and 70 together ( 40 * 70 = 2800 )Step 3: Divide the 2800 with 10. (2800/10 = 280)So, the LCM of 40 and 70 is 280

The simplest way to go about this, so you know you did not make a mistake is make a factor tree to find the LCM of both 40 and 18 so for 40 8-----5 4---2 2--2 LCM = 5*2*2*2 for 18 6----3 3---2 LCM = 3*3*2 LCM for 40 and 18 = 5*2*2*2*3*3=360 LCM would equal the LCD if you were using this to find lowest common denominator! LCD=360 so for 40 you would have to mulptiply 9 times and for 18 multiply 20 times! Hope this helps!
