HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 662, 457 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 662, 457 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 662, 457 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 662, 457 is 1.
HCF(662, 457) = 1
HCF of 662, 457 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 662, 457 is 1.
Highest Common Factor of 662,457 is 1
Step 1: Since 662 > 457, we apply the division lemma to 662 and 457, to get
662 = 457 x 1 + 205
Step 2: Since the reminder 457 ≠ 0, we apply division lemma to 205 and 457, to get
457 = 205 x 2 + 47
Step 3: We consider the new divisor 205 and the new remainder 47, and apply the division lemma to get
205 = 47 x 4 + 17
We consider the new divisor 47 and the new remainder 17,and apply the division lemma to get
47 = 17 x 2 + 13
We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get
17 = 13 x 1 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 662 and 457 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(47,17) = HCF(205,47) = HCF(457,205) = HCF(662,457) .
