HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 439, 4921 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 439, 4921 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 439, 4921 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 439, 4921 is 1.
HCF(439, 4921) = 1
HCF of 439, 4921 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 439, 4921 is 1.
Highest Common Factor of 439,4921 is 1
Step 1: Since 4921 > 439, we apply the division lemma to 4921 and 439, to get
4921 = 439 x 11 + 92
Step 2: Since the reminder 439 ≠ 0, we apply division lemma to 92 and 439, to get
439 = 92 x 4 + 71
Step 3: We consider the new divisor 92 and the new remainder 71, and apply the division lemma to get
92 = 71 x 1 + 21
We consider the new divisor 71 and the new remainder 21,and apply the division lemma to get
71 = 21 x 3 + 8
We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get
21 = 8 x 2 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 439 and 4921 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(71,21) = HCF(92,71) = HCF(439,92) = HCF(4921,439) .
