What is the least common factor of 28 and 40?
Answer: 1 The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1, 2, and 4; the least (smallest) common factor is 1.
What is the greatest common factor of 28 and 40?
Answer: 4Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method: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 28 are 1, 2, 4, 7, 14, and 28.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.The greatest common factor of the numbers 28 and 40 is 4.
What are the common factors and greatest common factor of 8 and 40?
Since 8 is a factor of 40, it is automatically the GCF and all of its factors are common.
What is the GCF of 28 20 and 40?
To find the GCF, you first need to break the numbers down into their prime factors: 28 = 2x2x7 20 = 2x2x5 40 = 2x2x2x5 The next step is to find any common prime factors. In this case, all three numbers have two 2s as prime factors. Multiply these and you get 4. Therefore the GCF of 28, 20 and 40 is 4.
What is the greatest common factor of 12 28 and 40?
The greatest common factor of 12, 28, and 40 is 4 To find the greatest common factor of numbers, you first need to split these numbers into their prime factors: 12 = 2x2x3 28 = 2x2x7 40 = 2x2x2x2x5 You then need to find which prime factors are shared between the numbers. In this case, each of the numbers uses two 2s, but no other numbers are common between them. So to find the GCF we simply multiply two 2s: 2x2=4 Thus the GCF of 12, 28 and 40 is 4.
