no. 98 does not end in 5 or 0 so it couldn't possibly have 5 as a factor. Speak to your teacher about this.
The greatest common factor of the numbers 5, 98 and 198 is 1.
For 35, 5 and 7 For 98, 2 and 7
Since 49 is a factor of 98, it is automatically the GCF.
No because 4 is not a factor of 98
The factors of 98: 1, 2, 7, 14, 49, 98
The greatest common factor of the numbers 5, 98 and 198 is 1.
For 35, 5 and 7 For 98, 2 and 7
It is: 1
The GCF is 1.
Look for common factors, and divide by a common factor, if you find any. In this case, the prime factors of 125 is 5x5x5, so 5 is the only prime factor. Since 5 is not a factor of 98, this can't be simplified.
140 = 2 x 5 x 14, 98 = 7 x 14 so HCF is 14
Use a factor tree. 98 49,2 7,7,2
Since 49 is a factor of 98, it is automatically the GCF.
The greatest common factor of 98 and 112 is 14.
The greatest common factor of 34 and 98 is 2.
Since 49 is a factor of 98, it is automatically the GCF.
The factor pairs of 98 are (1,98), (2,49), and (7,14).
