The Highest Common Factor (HCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF of 245 and 392, you would first factorize both numbers: 245 = 5 x 7 x 7 and 392 = 2 x 2 x 2 x 7 x 7. Then, identify the common factors between the two numbers, which are 7 and 7. Therefore, the HCF of 245 and 392 is 7 x 7 = 49.

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 are the factor pairs of 392?
There are six factor pairs: 392 = 1 x 392 392 = 2 x 196 392 = 4 x 98 392 = 7 x 56 392 = 8 x 49 392 = 14 x 28
What are the highest common factors of 245 and 140?
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 HCF of 680?
To have a HCF, you need at least 2 numbers. There is no HCF in just 1 number.
What is 20 percent off of 245 dollars?
20 percent off of 245 dollars = 19620% off of $245= 20% discount applied to $245= $245 - (20% * $245)= $245 - (0.20 * $245)= $245 - 49= 196
