The GCF of two numbers is 5. the LCM is 90 the numbers add up to 55 what are the 2 numbers?
45 and 10
How can you find the gcf of two numbers without knowing the factors?
If one of the numbers is a multiple of the other, the smaller number is the GCF. If the two numbers are prime numbers, the GCF is 1. If the numbers are consecutive, the GCF is 1. If the numbers are consecutive even numbers, the GCF is 2.
Can the GCF of a pair of numbers be equal to one of the numbers?
Yes, if one of the numbers is a factor of the other.
What is the GCF of 2 different prime numbers?
The GCF is 1.
The LCM of two numbes is 24 the gcf is 2 the numbers differ by 2 what are the numbers?
Since the numbers differ by 2 and the GCF is 2, they are consecutive even integers. So the numbers are 6 and 8.
What is the GCF of numbers 50 40 and 45?
The GCF is 2.
What is the GCF of 102 and 50?
factor out both numbers to get 102=2*3*17 50=2*5*5 the GCF is 2
What is the GCF for these numbers 3 and 5?
The GCF is 1.
What is the greatest common factor of 2 numbers is 5?
The GCF of 5 and 10 is 5.
What is the HCF for the number 4?
the GCF of 4 3 5 is 1
What 2 numbers have 5 as their GCF?
5 and 10 or 5 and any multiple of 5 for a start
What is the GCF of two numbers in 5?
The GCF of 5 and 10 is 5.
What is the gcf of the numbers 155 and 350?
The GCF is 5.
What is the GCF of the numbers 15 and 50?
The GCF is 5.
What is the gcf of 5 and 20 and 35?
The GCF of these three numbers is 5.
The GCF of two numbers is 5. the LCM is 90 the numbers add up to 55 what are the 2 numbers?

How do you use prime factorization to find the gcf of two numbers?
Write the numbers in their prime factorisations. the GCF is the product of the common primes (each time they appear). Example: 30 and 42 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Select the common factors. 2 x 3 = 6, the GCF Example: 24 and 60 24 = 2 × 2 × 2 × 3 60 = 2 × 2 × 3 × 5 GCF = 2 × 2 × 3 = 12 The prime 2 appears twice in both numbers. If you use the power format of the prime factorisation, the GCF is the product of each of the common primes to the LOWEST power across the numbers. For 24 and 60 this gives: 24 = 2³ × 3 60 = 2² × 3 × 5 → GCF = 2² × 3 = 12 As the lowest power of 2 across the numbers is 2², the lowest power of 3 across the numbers is 3 = 3¹, 5 is not common, but for completeness, 24 = 2³ × 3¹ × 5⁰ since 5⁰ = 1, so the lowest power of the prime 5 across the numbers is 5⁰: → GCF = 2² × 3¹ × 5⁰ = 4 × 3 × 1 = 12.
