HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 226 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 657, 226 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 657, 226 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 657, 226 is 1.
HCF(657, 226) = 1
HCF of 657, 226 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 657, 226 is 1.
Highest Common Factor of 657,226 is 1
Step 1: Since 657 > 226, we apply the division lemma to 657 and 226, to get
657 = 226 x 2 + 205
Step 2: Since the reminder 226 ≠ 0, we apply division lemma to 205 and 226, to get
226 = 205 x 1 + 21
Step 3: We consider the new divisor 205 and the new remainder 21, and apply the division lemma to get
205 = 21 x 9 + 16
We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get
21 = 16 x 1 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 657 and 226 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(205,21) = HCF(226,205) = HCF(657,226) .
