What is the gcf of 18 and 16 in math?
The GCF is 2. The prime factorization of 18 is 2x3x3 and the prime factorization of 16 is 2x2x2x2. They both have one 2 in common so that would be the greatest common factor.
What is the greatest common factor of 15 9 and 18?
The GCF of 9, 15, and 18 is 3. The prime factorization of 9 is 3*3. The prime factorization of 15 is 3*5 The prime factorization of 18 is 2*3*3 So the greatest common factor is 3.
The greatest number which divides 10698 6443 14995 leaving 18 35 43 as remainder respectively?
10698 ÷ gcf = n remainder 18 → gcf divides 10698 - 18 = 106806443 ÷ gcf = m remainder 35 → gcf divides 6443 - 35 = 640814995 ÷ gcf = k remainder 43 → gcf divides 14995 - 43 = 14952Therefore want gcf(10680, 6408, 14952) = 2136.Using prime factorization method:10680 = 2³ x 3 x 5 x 896408 = 2³ x 3² x 8914952 = 2³ x 3 x 7 x 89hcf = 2³ x 3 x 89 = 2136
Find 3 numbers whose GCF is 18?
You can multiply the number 18 by different numbers that are relatively prime, for example by different prime numbers.
What number pair has a GCF of 3 and a LCM of 90?
The prime factorization of 90 is 2 x 3² x 5. There must be a 3 in one number and 3² in the other, and no other common prime factors; thus the number pair could be: 3 and 90 6 and 45 9 and 30 15 and 18
What is the LCM and gcf of 18 and 360?
Product of two numbers a and b = LCM(a,b) x GCF(a,b)...(1)Here, product of 18 and 360 = 6480Now, we shall find GCF of 18 and 360 by using the method of prime factorization.Prime factorization of 18 = 2x3x3Prime factorization of 360 = 2x2x2x3x3x5It is clear from the prime factorization that gcf = 18Now using (1) we can find LCM:LCM(18,360) = Product of 18 and 360/GCF(18,360) = 6480/18 = 360So, LCM and GCF of 18 & 360 is 360 and 18.Also, it is important to note that 360 is divisible by 18 then GCF is 18 and LCM is 360.
What is the greatest common factor of 9 18 27 and 36?
