HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 326 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 326 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 639, 326 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 639, 326 is 1.
HCF(639, 326) = 1
HCF of 639, 326 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 639, 326 is 1.
Highest Common Factor of 639,326 is 1
Step 1: Since 639 > 326, we apply the division lemma to 639 and 326, to get
639 = 326 x 1 + 313
Step 2: Since the reminder 326 ≠ 0, we apply division lemma to 313 and 326, to get
326 = 313 x 1 + 13
Step 3: We consider the new divisor 313 and the new remainder 13, and apply the division lemma to get
313 = 13 x 24 + 1
We consider the new divisor 13 and the new remainder 1, and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 639 and 326 is 1
Notice that 1 = HCF(13,1) = HCF(313,13) = HCF(326,313) = HCF(639,326) .
