State 3 factors that will determine linear expansion?
Linear expansion depends upon three factors: 1. Length of rod 2. Change in temperature 3. Nature of material of the rod.
What are the common factor of 21 and 27?
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and 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 27 are 1, 3, 9, and 27. The common factors are 1 and 3. This means that the greatest common factor is 3.
What are the common factors of 15 45 75?
The common factors of 15, 45, and 75 are the numbers that can evenly divide all three of these numbers. To find the common factors, you can first determine the prime factors of each number: 15 = 3 x 5, 45 = 3 x 3 x 5, and 75 = 3 x 5 x 5. The common factors are the numbers that appear in the prime factorization of all three numbers, which in this case are 3 and 5.
What are the common factor of 42 and 63?
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 63 are 1, 3, 7, 9, 21, and 63. The common factors are 1, 3, 7, and 21.
What is the least common multiple of 90 and 60?
To determine the least common multiple of two numbers, determine the prime factors of both numbers. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 60 are 2, 2, 3, and 5. The prime factors of 90 are 2, 3, 3, and 5. The prime factors in common are 2, 3, and 5, so the greatest common factor is 2 x 3 x 5 = 30. The least common multiple is thus (2 x 2 x 3 x 5) x (2 x 3 x 3 x 5) ÷ (2 x 3 x 5) or 60 x 90 ÷ 30 = 180. A similar way to use the prime factors is to take the prime factors of one number and cross out any that appear in the other number, then multiply the remaining ones together to calculate the least common multiple. 60 has 2, 2, 3, and 5 90 are 2, 3, 3, and 5 The least common multiple of 60 and 90 is 2 x 2 x 3 x 5 x 3 = 180.
