To find the highest common factor (HCF) of 245 and 140, we need to determine the largest number that divides both 245 and 140 without leaving a remainder. The factors of 245 are 1, 5, 7, 35, 49, and 245. The factors of 140 are 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, and 140. The common factors of 245 and 140 are 1, 5, and 35. Therefore, the highest common factor of 245 and 140 is 35.

What is the highest common factor of 350 and 245?
The highest common factor (HCF) of two numbers is the largest number that divides both numbers without leaving a remainder. To find the HCF of 350 and 245, we can use the Euclidean algorithm. Dividing 350 by 245, we get a quotient of 1 and a remainder of 105. Now, we divide 245 by 105, which gives us a quotient of 2 and a remainder of 35. Finally, dividing 105 by 35, we get a quotient of 3 and a remainder of 0. Therefore, the highest common factor of 350 and 245 is 35.
What is the greatest common factor of 128 and 245?
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 both numbers have in common. 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 128 are 1, 2, 4, 8, 16, 32, 64, and 128. The factors of 245 are 1, 5, 7, 35, 49, and 245. The only common factor is 1. Therefore, the greatest common factor is 1.
What are the highest common factors of 490 and 1750?
To find the highest common factor (HCF) of 490 and 1750, you can first list the factors of each number. The factors of 490 are 1, 2, 5, 7, 10, 14, 35, 70, 98, 245, and 490. The factors of 1750 are 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 125, 175, 250, 350, 875, and 1750. The common factors between the two lists are 1, 2, 5, 7, 10, 14, and 35. Therefore, the highest common factor of 490 and 1750 is 35.
What is the greatest common factor of 735 and 2625?
735/3=245/7=35/7=5 2625/3=875/7=125/5=25/5=5 ring the factors in common which are 3*7*5 =105 highest common factor
What are the factors for 245?
