1 and 5
The GCF of 30 and 35 is 5.One way to approach this is to look at the difference between 30 and 35, which is 5. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. Since both 30 and 35 are divisible by 5, the greatest common factor is 5.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 35 are 1, 5, 7, and 35.The common factors are 1 and 5. Therefore, the greatest common factor is 5.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 30 are 2, 3, and 5.The prime factors of 35 are 5 and 7.The prime factors in common are a single 5, so the greatest common factor is 5.The GCF is 5.
1,5,7,35Since 35 is a factor of 70, all of its factors are common.
The common factors of 35 and 75 are 1,and 5.
Since 35 is a factor of 140, all of its factors are common.
Since 35 is a factor of 70, all of its factors are common.
The factors of: 27: 1, 3, 9, 27 35: 1, 5, 7, 35 30: 1, 2, 3, 5, 6, 10, 15, 30 Common factors: cf(27, 35): 1 cf(27, 30): 1, 3 cf(35, 30): 1, 5 cf(27, 35, 30): 1 27 = 3^3 35 = 5 x 7 30 = 2 x 3 x 5 The common factors are the factors of their highest common factor: hcf(27, 35) = 1 → cf(27, 35): 1 hcf(27, 30) = 3 → cf(26, 30): 1, 3 hcf(35, 30) = 5 → cf(35, 30): 1, 5 hcf(27, 35, 30) = 1 → cf(27, 35, 30): 1
The GCF is 5.
5 is the HCF
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 21 are 1, 3, 7, and 21. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 35 are 1, 5, 7, and 35. There is only one common factor: 1. Therefore, the greatest common factor is 1. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 21 are 3 and 7. The prime factors of 30 are 2, 3, and 5. The prime factors of 35 are 5 and 7. There are no prime factors in common, so the greatest common factor is 1.
The common factors are: 1, 7
The common factors of 35 and 60 are 1 and 5.
