Use a factor tree. 98 49,2 7,7,2
Since 49 is a factor of 98, it is automatically the GCF.
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
No because 4 is not a factor of 98
