LCD(42, 54) = 378
42 as that number is the smallest number that both 3 and 14 will go into.
The least common factor of 30 and 42 is the smallest number that is a factor of both of them and is 1.However, I suspect that you mean either:What is the highest common factor of 30 and 42?ie what is the highest number that is a factor of both 30 and 42: hcf = 6;What is the lowest common multiple of 30 and 42?ie that is the smallest number that is a multiple of both 30 and 42 lcm = 210.
Well, honey, the least common multiple (LCM) of 14 and 42 is 42. Why? Because 42 is a multiple of both 14 and 42, and it's the smallest number that fits the bill. So, there you have it, simple math for ya!
The smallest number that can be divided by both 30 and 42 is 210.
The least common multiple (LCM) of two numbers is the smallest positive rational number (not zero) that is a multiple of both. Multiples of 14 are: 14, 28, 42, 56, etc. Multiples of 21 are: 21, 42, 63,etc. The least common multiple of 14 and21 is the smallest one of those: 42
arithmetic and number theory, the least common multiple(also called the lowest common multiple or smallest common multiple) of two integers a and b, usually denoted by LCM(a, b), is the smallest positive integer that is a multiple of both a and b.LCM(63,42)=126
To find the lowest common multiple (LCM) of two numbers, we first need to find the prime factorization of each number. The prime factorization of 42 is 2 x 3 x 7, and the prime factorization of 49 is 7 x 7. To find the LCM, we take the highest power of each prime factor that appears in either number, which gives us 2 x 3 x 7 x 7 = 294. Therefore, the lowest common multiple of 42 and 49 is 294.
