HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 245, 4291 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 245, 4291 is 7 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 245, 4291 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 245, 4291 is 7.
HCF(245, 4291) = 7
HCF of 245, 4291 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 245, 4291 is 7.
Highest Common Factor of 245,4291 is 7
Step 1: Since 4291 > 245, we apply the division lemma to 4291 and 245, to get
4291 = 245 x 17 + 126
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 126 and 245, to get
245 = 126 x 1 + 119
Step 3: We consider the new divisor 126 and the new remainder 119, and apply the division lemma to get
126 = 119 x 1 + 7
We consider the new divisor 119 and the new remainder 7, and apply the division lemma to get
119 = 7 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 245 and 4291 is 7
Notice that 7 = HCF(119,7) = HCF(126,119) = HCF(245,126) = HCF(4291,245) .
