HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1617, 4462 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1617, 4462 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 1617, 4462 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 1617, 4462 is 1.
HCF(1617, 4462) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1617, 4462 is 1.
Step 1: Since 4462 > 1617, we apply the division lemma to 4462 and 1617, to get
4462 = 1617 x 2 + 1228
Step 2: Since the reminder 1617 ≠ 0, we apply division lemma to 1228 and 1617, to get
1617 = 1228 x 1 + 389
Step 3: We consider the new divisor 1228 and the new remainder 389, and apply the division lemma to get
1228 = 389 x 3 + 61
We consider the new divisor 389 and the new remainder 61,and apply the division lemma to get
389 = 61 x 6 + 23
We consider the new divisor 61 and the new remainder 23,and apply the division lemma to get
61 = 23 x 2 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1617 and 4462 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(61,23) = HCF(389,61) = HCF(1228,389) = HCF(1617,1228) = HCF(4462,1617) .
Here are some samples of HCF using Euclid's Algorithm calculations.
