The greatest common factor (GCF) of 15 and 35 will be 5.
Greatest Common Factor is defined as the greatest number that is a factor of both numbers when two numbers are involved.
To find the GCF using prime factorization, list all of the prime factors of each integer or use a Prime Factors. List the prime factors that are shared by all of the original numbers. Include the most instances of each prime component that is common to each original number. Add these to get the GCF.
The prime factorization of 15 is 3 x 5 = 15.
The prime factorization of 35 is 5 x 7 = 35.
The occurrences of common prime factors of 15 and 35 is 5.
Thus, the greatest common factor (GCF) of 15 and 35 will be 5.

Answer:
AB = 17.3 cm
Step-by-step explanation:
We require to find the measure of ∠A then use the cosine ratio to calculate AB
sum the parts of the ratio 3 + 2 = 5 parts, then
90° ÷ 5 = 18° ← value of 1 part of ratio
∠A = 2 × 18° = 36°, thus
cos36° = =
Multiply both sides by AB
AB × cos36° = 14 ( divide both sides by cos36° )
AB = ≈ 17.3 cm
Answer:
m
Step-by-step explanation:
1 meter = 100 centimeters
50 cm =
50 cm =
Original length =
Decrease the original length by 50 cm
So, Length =
=
=
=
Hence new length is m
