The least common factor of any two or more positive numbers is always 1.
The greatest common factor of 35 and 63 is 7.
The greatest common factor (GCF) is 1.
The factors of 35 are 1, 5, 7, and 35. The factors of 81 are 1, 3, 9, 27, and 81. The only factor they have in common is 1. Therefore, 1 is the greatest common factor. This means that 35 and 81 are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 35 are 5 and 7. The prime factors of 81 are 3, 3, 3, and 3. They have no prime factors in common, so they are relatively prime, which means the only factor they have in common is 1.
The GCF is 1.
25 = 5*5 35 = 5*7 45 = 3*3*5 So the greatest common factor is 5.
The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 35 are 1, 5, 7, and 35.The only common factor is 1, so the greatest common factor is 1. This means they are relatively prime.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 18 are 2, 3, and 3.The prime factors of 35 are 5 and 7.There are no common prime factors, therefore they are relatively prime, which means the greatest common factor is 1.18 = 2 x 3 x 3, 35 = 5 x 7. There is no common factor other than 11 - they are relatively primeThe GCF is 1.The GCF is 1.The GCF is 1.
The factors of 35 are 1, 5, 7, and 35. The factors of 27 are 1, 3, 9, and 27. The only factor they have in common is 1; therefore, 35 and 27 are relatively prime. Alternatively, you can look at the prime factors. The prime factors of 35 are 5 and 7. The prime factors of 27 are 3, 3, and 3. They have no prime factors in common, so they are relatively prime, which means their only common factor is 1.
1 The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 35 are 1, 5, 7, and 35. The only common factor of 24 and 35 is 1. Therefore, the least (smallest) common factor is 1, and the greatest (highest) common factor is 1.
3 is not a factor of 35
3/35 is already in lowest terms (there is no common factor other than 1 between 3 and 35).
15 = 5*3 35 = 5*7 GCF: 5 (and the only comon factor)
21 = (3)(7)35 = (5)(7)7
