1, 2, 4, 5, 8, 10, 20, 40.
1 is the only number that goes into 29 and 40.
The number is 1.
The HCF of 38 and 40 is 2
It is: 1
11/33
2.
It is 8
25=5x5 40=2x2x2x5 5 is the common factor
Their highest common factor is 4
The common factors are: 1, 5
The number of times 40 goes into 90 can be determined by dividing 90 by 40. Performing the division, we find that 40 goes into 90 two times with a remainder of 10. Therefore, 40 goes into 90 a total of 2 times.
Firstly, a factor of a number is another number that you can divide it by and get a whole number. The factors of 40 are: 1,2,4,5,8,10,20 and 40 The factors of 30 are: 1,2,3,5,6,10,15 and 30 Now, to find the GREATEST common factor of 40 and 30 , we would have to find the biggest number that goes into both 40 AND 30. After reading the factors above, we can see that 10 is the highest number that goes into both numbers, therefore 10 is the greatest common factor of 40 and 30.
