7 is a factor of 28 because 4 x 7 equals 28. 7 is a factor of 63 because 9 x 7 = 63. That makes 7 a common factor of 28 and 63. The factors of 28 that are larger than 7 are 14 and 28. The factors of 63 that are larger than 7 are 9, 21 and 63. Since none of those numbers are the same, that makes 7 the greatest common factor of 28 and 63.
There are two numbers, 7 and 49, whose smallest prime factor is 7 in the set of numbers from 1 to 100.
5 x 7 x 11 = 385
Besides 1, the factor of 3 is 3. Besides 1, the factor of 7 is 7. Besides 1, the factors of 9 are 3 and 9.
Since 7 is a factor of 28 itself. Therefore the lowest common multiple will be 28.
The smallest multiply of 7 divisible by 9 is the lowest common multiple of 7 and 9: lcm(7, 9) = 63.
One
The smallest "non common" factors of 180 and 600 are: 7 - is not a factor of either 8 - is only a factor of 600 9 - is only a factor of 180
Answer: 1 The factors of 9 are 1, 3, and 9. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3; the least (smallest) common factor is 1.
7 The factors of 49 are 1, 7, and 49. The least (or smallest) factor is 1.
7 is a factor of 28 because 4 x 7 equals 28. 7 is a factor of 63 because 9 x 7 = 63. That makes 7 a common factor of 28 and 63. The factors of 28 that are larger than 7 are 14 and 28. The factors of 63 that are larger than 7 are 9, 21 and 63. Since none of those numbers are the same, that makes 7 the greatest common factor of 28 and 63.
It is: 36
63 is the smallest multiple of 7 and 9
The greatest common factor must be a factor of the smallest number. The smallest number is 7. Its factors are 1 and 7. So the greatest common factor must be either 1 or 7. Since 7 is the larger of the two factors, check whether it is a factor of the additional numbers. Since it is, 7 is the greatest common factor.
The answer is 16. The range is the difference between the largest and smallest values: Largest: 7 Smallest: -9 Difference = 7 - (-9) = 16
There are two numbers, 7 and 49, whose smallest prime factor is 7 in the set of numbers from 1 to 100.
The least common factor of any set of numbers is 1.
