Oh, what a lovely collection of numbers you have there! Let's see, a factor is a number that can be divided evenly into another number. For these numbers, the factors are 1, the number itself, and any other numbers that divide evenly into them. Take your time exploring the beautiful patterns and relationships between these numbers, and remember, there's no mistakes in math, just happy little accidents.
Both of these numbers are divisible by 3 and 7. The factors of 105 is 21 x 5 and that of 147 is 21 x 7. So the LCM is 21 x 35 = 735.
1 x 735, 3 x 245, 5 x 147, 7 x 105, 15 x 49, 21 x 35
1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945 3, 5 and 7 are prime.
To find the highest common factor (HCF) of 735 and 945, we first need to factorize both numbers. The prime factors of 735 are 3 x 5 x 7 x 7, and the prime factors of 945 are 3 x 3 x 3 x 5 x 7. To find the HCF, we identify the common prime factors and multiply them together: 3 x 5 x 7 = 105. Therefore, the highest common factor of 735 and 945 is 105.
The GCF of 105 and 189 is 21.
The greatest common factor of 105 and 147 is 21
To find the greatest common factor (GCF) of 84, 105, and 147, you need to identify the common factors of these numbers. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The factors of 105 are 1, 3, 5, 7, 15, 21, 35, and 105. The factors of 147 are 1, 3, 7, 21, 49, and 147. The greatest common factor among these three numbers is 21.
1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
The composite factors of 735 are 15, 21, 35, 49, 105, 147, 245, 735
1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735.
1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735.
To find the greatest common factor of two numbers, you first need to break those numbers down into their prime factors. For 105 and 147 this is: 105 = 3x5x7 147 = 3x7x7 The next step is to identify any common prime factors. In this case, both numbers have a 3 as a prime factor, and a 7 as a prime factor. Multiply these together to get the GCF: 3x7 = 21 Thus the greatest common factor of 105 and 147 is 21.
The factors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105The factors of 147 are: 1, 3, 7, 21, 49, 147The common factors are: 1, 3, 7, 21The Greatest Common Factor (GCF) is: 21
The GCF of 105 and 147 is 21. Dividing 21 into each of these gives 5 and 7 respectively. These are not further divisible by any number except for 1.
1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735.
21
The divisors of 735 are 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, and 735.
