Step-by-step explanation:
find gcf (45 and 30) = ?
the prime factors of 45 and 30 are
45 = 3 x 3 x 5
30 = 2 x 3 x 5
The common prime factor or the product of all common prime factors between all integers is the highest common factor of this group of integers (45 & 30).
GCF(45, 30) = 15
----------------------------------------------
find gcf (16 and 48) = ?
the prime factors of 16 and 48 are
16 = 2 x 2 x 2 x 2
48 = 2 x 2 x 2 x 2 x 3
The common prime factor or the product of all common prime factors between all integers is the highest common factor of this group of integers (16 & 48).
GCF(16, 48) = 16
---------------------------------------------
find gcf (39 and 25) = ?
the prime factors of 39 and 25 are
39 = 3 x 13
25 = 5 x 5
There is no common factors between the integers, therefore the GCF (39 & 25) is equal to 1.
GCF(39, 25) = 1
----------------------------------------------
find gcf (49 and 56) = ?
the prime factors of 49 and 56 are
49 = 7 x 7
56 = 2 x 2 x 2 x 7
The common prime factor or the product of all common prime factors between all integers is the highest common factor of this group of integers (49 & 56).
GCF(49, 56) = 7
----------------------------------------------
find gcf (120 and 144) = ?
Find the prime factors of 120 and 144 are
120 = 2 x 2 x 2 x 3 x 5
144 = 2 x 2 x 2 x 2 x 3 x 3
The common prime factor or the product of all common prime factors between all integers is the highest common factor of this group of integers (120 & 144).
GCF(120, 144) = 24
----------------------------------------------
1st 5 are solved in detail..
Do the next 5 in same manner. Answers of next 5 are:
gcf (81 and 99) = 9
gcf (24 and 36) = 12
gcf (25 and 75) = 25
gcf (48 and 54) = 6
gcf (150 and 225) = 75
