HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 4426 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 391, 4426 is 1 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 391, 4426 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 391, 4426 is 1.
HCF(391, 4426) = 1
HCF of 391, 4426 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 391, 4426 is 1.
Highest Common Factor of 391,4426 is 1
Step 1: Since 4426 > 391, we apply the division lemma to 4426 and 391, to get
4426 = 391 x 11 + 125
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 125 and 391, to get
391 = 125 x 3 + 16
Step 3: We consider the new divisor 125 and the new remainder 16, and apply the division lemma to get
125 = 16 x 7 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 391 and 4426 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(125,16) = HCF(391,125) = HCF(4426,391) .
