What is the greatest common factor of 13 39 52 and 78?
which pair of nummber has GCF that is a prime number 48 and 90 or 105 and 56?
What is a factor tree of 78?
78 6 x 13 (2x3) x 13 Since 2, 3, and 13 are prime numbers, the factor tree is complete.
What two digit numbers have the most factors in their prime factorization?
One way to solve this is to multiply the lowest prime numbers together, starting from 2: 2x3=6. 6x5=30. Multiplying by 7 would yield a 3-digit number, so we are looking for all 2-digit numbers with 3 distinct prime factors. We already have 30. 2x3x7=42. 2x3x11=66. 2x3x13=78. 2x5x7=70. So, to answer the original question, the 2-digit numbers that have the most factors in their prime factorization are, in ascending order, 30, 42, 66, 70, and 78.

Are 78 and 13 relatively prime?
No. Numbers that are relatively prime, only have the number 1 as a common factor. 13 and 78 have 1 and 13 as common factors, so they are not relatively prime.

How can you know if 6 is a factor of 78?
For a number to be divisible by 6, it has to be divisible by 2 and 3, because 2*3=6.In other words, we could divide the number we're factorising (78) by the prime factors of the number we're testing (6, which is 2*3). We start by dividing by 2, because we know 78 is even: 78/2=39. Then, we divide the new number by the other prime factor - 3. 39/3=13 13 is a whole number with no remainders, therefore we can say that 78 is divisible by 6, and therefore 6 is a factor of 78. (6*13=78)
What is the prime number and product of 78?
The prime factorization of 78 is 2x3x13.
What is the greatest common factor for 17 43 83?
