HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 2653 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 657, 2653 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, 2653 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, 2653 is 1.
HCF(657, 2653) = 1
HCF of 657, 2653 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, 2653 is 1.
Highest Common Factor of 657,2653 is 1
Step 1: Since 2653 > 657, we apply the division lemma to 2653 and 657, to get
2653 = 657 x 4 + 25
Step 2: Since the reminder 657 ≠ 0, we apply division lemma to 25 and 657, to get
657 = 25 x 26 + 7
Step 3: We consider the new divisor 25 and the new remainder 7, and apply the division lemma to get
25 = 7 x 3 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 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 657 and 2653 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(25,7) = HCF(657,25) = HCF(2653,657) .
