2 will.
The only whole number that can go in both 5 and 42 is 1 since these numbers are co-prime.
252 is the LCM
7y-42=28 ==> 7y=42+28 => y=70/7. => 10
The largest whole number that can go into these three number, 28, 42, and 70 is:142 times 14 equals 283 times 14 equals 425 times 14 equals 70Or it could be 28 if you allowed non-whole numbers in the equation:1 times 28 equals 281.5 times 28 equals 422.5 times 28 equals 70
Both 21 and 14 can go into their least common multiple, which is 42. Additionally, they can both go into any multiple of 42, such as 84, 126, and so on. Furthermore, they can also share common factors, such as 1 and 7, but in terms of multiples, 42 is the smallest number they both divide into evenly.
42 as that number is the smallest number that both 3 and 14 will go into.
Find factors that can go into both numbers. The most obvious that can do this is 2. So 84/166 = 42/83 No other number can go into both 42 and 83.
14 and 28 can both go into any multiple of 28 .
42, it has to be an even number because of the 2, so just methodically go through the 7 times table, eg 14, 28, 42
1 2 4 7 14 28
12: 1 2 3 4 6 7 12 14 21 28 42 84.
42 with remainder 14.
