WebDetailed Answer: The Greatest Common Factor (GCF) for 147 and 245, notation CGF (147,245), is 49. Explanation: The factors of 147 are 1,3,7,21,49,147; The factors of 245 are 1,5,7,35,49,245. So, as we can see, the Greatest Common Factor or Divisor is 49, because it is the greatest number that divides evenly into all of them. WebHighest Common Factor of 70,130 is 10. Step 1: Since 130 > 70, we apply the division lemma to 130 and 70, to get. Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 60 and 70, to get. Step 3: We consider the new divisor 60 and the new remainder 10, and apply the division lemma to get. The remainder has now become zero, so our ...
What is the greatest common factor of 145 and 245?
WebTo get the prime factorisation of 245, we have to start with dividing it by primes. 245 ÷ 49 = 5. 49 ÷ 7 = 7. 7 ÷ 1 = 7. So here he prime factorisation of 245 = 5 x 7 x 7 = 5 1 x 7 2. We can check it in a prime factorisation calculator also. The algorithm used in the calculator and trial division may differ but the result is always the same. WebDetailed Answer: The Greatest Common Factor (GCF) for 145 and 245, notation CGF (145,245), is 5. Explanation: The factors of 145 are 1,5,29,145; The factors of 245 are 1,5,7,35,49,245. So, as we can see, the Greatest Common Factor or Divisor is 5, because it is the greatest number that divides evenly into all of them. northeast queensland
Find HCF of $70$ and $245$ using Fundamental Theorem …
WebHCF (70, 105, 175) can be thus calculated by first finding HCF (70, 105) using long division and thereafter using this result with 175 to perform long division again. Step 1: Divide … WebSo, follow the step by step explanation & check the answer for HCF(45,70). Here 70 is greater than 45. Now, consider the largest number as 'a' from the given number ie., 70 … Web245 = 5 × 7 × 7. To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 5 × 7. GCF = 35.
