HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 623, 12632 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 623, 12632 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 623, 12632 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 623, 12632 is 1.
HCF(623, 12632) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 623, 12632 is 1.
Step 1: Since 12632 > 623, we apply the division lemma to 12632 and 623, to get
12632 = 623 x 20 + 172
Step 2: Since the reminder 623 ≠ 0, we apply division lemma to 172 and 623, to get
623 = 172 x 3 + 107
Step 3: We consider the new divisor 172 and the new remainder 107, and apply the division lemma to get
172 = 107 x 1 + 65
We consider the new divisor 107 and the new remainder 65,and apply the division lemma to get
107 = 65 x 1 + 42
We consider the new divisor 65 and the new remainder 42,and apply the division lemma to get
65 = 42 x 1 + 23
We consider the new divisor 42 and the new remainder 23,and apply the division lemma to get
42 = 23 x 1 + 19
We consider the new divisor 23 and the new remainder 19,and apply the division lemma to get
23 = 19 x 1 + 4
We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get
19 = 4 x 4 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 623 and 12632 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(23,19) = HCF(42,23) = HCF(65,42) = HCF(107,65) = HCF(172,107) = HCF(623,172) = HCF(12632,623) .
Here are some samples of HCF using Euclid's Algorithm calculations.
