The factors of 98: 1, 2, 7, 14, 49, 98
Use a factor tree. 98 49,2 7,7,2
Two ways to approach this problem:Factor out the given term prime by prime.Factor out the term by the number you really know that divides that number!Then, 98 is factored to:98 = 2 * 49= 2 * 7 * 7= 2 * 7²
Since 49 is a factor of 98, it is automatically the GCF.
No because 4 is not a factor of 98
98
Yes, it is.
Use a factor tree. 98 49,2 7,7,2
no 90 93 96 99 102 so not 98
No
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 90 and 98 is 2
