HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 233 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 644, 233 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 644, 233 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 644, 233 is 1.
HCF(644, 233) = 1
HCF of 644, 233 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 644, 233 is 1.
Highest Common Factor of 644,233 is 1
Step 1: Since 644 > 233, we apply the division lemma to 644 and 233, to get
644 = 233 x 2 + 178
Step 2: Since the reminder 233 ≠ 0, we apply division lemma to 178 and 233, to get
233 = 178 x 1 + 55
Step 3: We consider the new divisor 178 and the new remainder 55, and apply the division lemma to get
178 = 55 x 3 + 13
We consider the new divisor 55 and the new remainder 13,and apply the division lemma to get
55 = 13 x 4 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 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 644 and 233 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(55,13) = HCF(178,55) = HCF(233,178) = HCF(644,233) .
