Least common multiple (LCM) is the is the multiple of the highest power of prime factors in the given numbers. For example, LCM of 4, 8, and 12 = 2 3 x 3 = 8 x 3 = 24. Th…e LCM is the smallest number that each of your given numbers will go into. So, 4 will divide into 12 but 8 won't. If you're not comfortable with prime numbers, which is the best way to approach this problem, try stepping up one each time. 12 x 2 = 24. 4 will divide into 24 and so will 8. So 24 is the LCM of those three numbers. The LCM, or least common multiple, is the smallest positive wholenumber exactly divisible by two or more given whole numbers.Example: the LCM of 14 and 35 is 70 because 70/14=5 and 70/35=2,and no number smaller than 70 is exactly divisible by 14 and 35. LCM is Lowest Common Multiple or Least Common Multiple. It is the Lowest (whole) number (greater than 0) that is a multipleof all the other (whole) numbers. It is sometimes referred to as the LCD or Lowest Common Denominatorwhen dealing with fractions and trying to find the (lowest)denominator to use for equivalent fractions (so that all thefractions have the same denominator for addition or subtraction ofthe fractions). By using the LCM of the denominators it keeps thenumerators of the equivalent fractions as small as possible. ( Full Answer )

You were so close. All you had to do was write down two numbers and you would have had a better answer than this one.

The formula, which is simpler to apply than to write out(!) is If X1 = p a1 q b1 r c1 ... and X2 = p a2 q b2 r c2 ... where p, q, r etc are prime numbers and a, b, c e…tc are integers. Then LCM(X1, X2) = p max(a1,a2) *q max(b1,b2) *r max(c1,c2) ... ( Full Answer )

easy......two because the factors of 10 are 2 and 5 and the factors of 12 are 2 and 4

That depends upon the other number(s), but it will always be a multiple of 35.

You can't find the LCM of a single number. You need at least two. If that's 122 and 237, the LCM is 28914. If that's 12, 22 and 37, the LCM is 9768.

Dividing the number with the highest possible divisible. That means find the GCF of the 2 numbers and then divide the GCF to one of the numbers and multiply it to te other. EX…AMPLE : Whats is the LCM of 4 and 6 ? step 1. Find the GCF( Greatest Common Factor) of 4 and 6. So the GCF of 4 and 6 is 2. step 2. Divide any of the number by the GCF of 4 an 6 ( which is 2). 4 divided by 2 is 2. Or 6 divided by 2 is 3. step 3. Multiply the number you got at step.2 with the other one. If you divided 4 by 2 (2 is the GCF of 4 and 6) the answer was 2. So multiply 2 by the number that is left ( in this case 6 ) so 2 x 6 is 12. 12 IS THE LCM f 4 and 6. If you divided 6 by 2 ( 2 is the GCF of 4 and 6) then you end up with 3. Thererfor, the only number left is 4 so you multiply 3 by 4 and you end up with 12. You will get the same answer !
