Yes.
Divide the factor into the number. If the answer is a whole number, the factor is a factor.
When finding the factors of 841, the largest number you would test is 29. No prime number higher than 29 could be a factor because the square of that number would exceed 841.
#1 For any EVEN number it will divide by '2'. So '2' is a factor. e.g. 1,000,004 #2 For any number ending in '5' or '0' it will divide by '5'. So ;5; is a factor. e.g. 505, or 1050 #3 For any number where the digits sum/add to '9' , then it will divide by '9'. So '9' is a factor. e.g. 153 ( 1 + 5 + 3 = 9) #4 For any number where the inside digits sum to the total of the outside digits, then '11' is a factor . e.g. 132 (1 + 2 = 3) #5 The only two numbers you MUST test mechanically are '3' & '7'.
Divide the smaller number into the bigger number. If the answer comes out even with no remainder, it's a factor.

Divide 291 by 7 and see if you get a whole number or is there a remainder. If it is not a whole number, then it is not a factor. 7 goes into 291 41 times with a remainder of 4, so it is not a factor.
it's simple, you divide the potential factor by the original number.For example, if I wanted to find out if 12 was a factor of 36;36/12= 3Because this number is an integer and not a decimal we know that in fact, 12 is a factor of 36.I hope that helped :)

compaction factor test is better than slump test,because compaction factor test should have own compaction wight,so correct value will be find out from compaction factor test.........
