HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 23 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 634, 23 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 634, 23 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 634, 23 is 1.
HCF(634, 23) = 1
HCF of 634, 23 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 634, 23 is 1.
Highest Common Factor of 634,23 is 1
Step 1: Since 634 > 23, we apply the division lemma to 634 and 23, to get
634 = 23 x 27 + 13
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 13 and 23, to get
23 = 13 x 1 + 10
Step 3: We consider the new divisor 13 and the new remainder 10, and apply the division lemma to get
13 = 10 x 1 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 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 634 and 23 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(634,23) .
