To check if a number is divisible by 4 quickly and easily, you only look at the tens and units. You divide these by 2 and if the result is even, the whole number is divisible by 4. In this case, you take 60, divide it by 2 to get 30, which is even. Thus 1260 is divisible by 4.
Every number below is a factor of 1260 achieved in a systematic fashion. You should be able to do 1350 now. Factors of 1260 = 1260 * 1 630 * 2 420 * 3 315 * 4 252 * 5 210 * 6 180 * 7 140 * 9 126 * 10 105 * 12 90 * 14 84 * 15 70 * 18 63 * 20 60 * 21 45 * 28 42 * 30 35 * 36

The smallest number with exactly 36 factors is 1260. The factors are: 1, 2, 3, 4, 5, 6, 7, 9, 10, 12, 14, 15, 18, 20, 21, 28, 30, 35, 36, 42, 45, 60, 63, 70, 84, 90, 105, 126, 140, 180, 210, 252, 315, 420, 630, and 1260.
The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. To find the two numbers with an LCM of 1260, we need to factorize 1260 into its prime factors, which are 2, 2, 3, 3, 5, and 7. We then pair these prime factors to form two numbers, such as 2 x 2 x 3 x 5 = 60 and 3 x 7 = 21. Therefore, the two numbers with an LCM of 1260 are 60 and 21.
assuming -1 is a valid factor then the others are 2,2,7,9
