I'll guess those are three-digit numbers. The way to find if a number is a multiple of 3 is to total its digits. If that total is a multiple of 3, the whole number is a multiple of 3. 285 and 126, yes. 770, 176, 410, 452, 650, no.
285
285 is divisible by these numbers: 1, 3, 5, 15, 19, 57, 95, 285.
285 = 3*5*19.
285
95
Least Common Multiple (LCM) for 57 27 is 513
It would help to have that other number. If the other number is a multiple of 3, the LCM is that number. If it is not a multiple of 3, the LCM is 3 times that number.
285 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 285 are 1, 3, 5, 15, 19, 57, 95, and 285.The factor pairs of 285 are 1 x 285, 3 x 95, 5 x 57, and 15 x 19.The proper factors of 285 are 1, 3, 5, 15, 19, 57, and 95 or,if the definition you are using excludes 1, they are 3, 5, 15, 19, 57, and 95.The prime factors of 285 are 3, 5, and 19.The 3 distinct prime factors (listing each prime factor only once) of 285 are 3, 5, and 19.The prime factorization of 285 is 3 x 5 x 19.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.The prime factors of 285 are: 3,5,19
No, 92 is not a multiple of 3. A quick way to check if a number is a multiple of 3 is: add up the digits of the number you are checking; if this sum equals 3 or a multiple of 3, then the number is a multiple of 3. So in this case, 92 --> 9+2=11, which is not a multiple of 3. If you have to you can add again, so for 11 --> 1+1=2, which is not a multiple of 3. You can always repetitively add until you get to a single digit answer: if it's 3,6 or 9 then it's a multiple of 3. Also if your sum is 9 or a multiple of 9, then the original number is a multiple of 9. To check for 6, if a number is a multiple of 3, and also a multiple of 2 (an even number), then the number is a multiple of 6.
No. To find if a number is a factor of 3, add the number's digits. If the resulting number is a multiple of 3, then the original number is a multiple of 3. In 4339, the digits of the number added together is 19, which is not a multiple of 3.
The least common multiple (LCM) of 240 and 285 is 4560.
