HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 565 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 657, 565 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, 565 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, 565 is 1.
HCF(657, 565) = 1
HCF of 657, 565 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, 565 is 1.
Highest Common Factor of 657,565 is 1
Step 1: Since 657 > 565, we apply the division lemma to 657 and 565, to get
657 = 565 x 1 + 92
Step 2: Since the reminder 565 ≠ 0, we apply division lemma to 92 and 565, to get
565 = 92 x 6 + 13
Step 3: We consider the new divisor 92 and the new remainder 13, and apply the division lemma to get
92 = 13 x 7 + 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 657 and 565 is 1
Notice that 1 = HCF(13,1) = HCF(92,13) = HCF(565,92) = HCF(657,565) .
