HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 656, 403 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 656, 403 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 656, 403 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 656, 403 is 1.
HCF(656, 403) = 1
HCF of 656, 403 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 656, 403 is 1.
Highest Common Factor of 656,403 is 1
Step 1: Since 656 > 403, we apply the division lemma to 656 and 403, to get
656 = 403 x 1 + 253
Step 2: Since the reminder 403 ≠ 0, we apply division lemma to 253 and 403, to get
403 = 253 x 1 + 150
Step 3: We consider the new divisor 253 and the new remainder 150, and apply the division lemma to get
253 = 150 x 1 + 103
We consider the new divisor 150 and the new remainder 103,and apply the division lemma to get
150 = 103 x 1 + 47
We consider the new divisor 103 and the new remainder 47,and apply the division lemma to get
103 = 47 x 2 + 9
We consider the new divisor 47 and the new remainder 9,and apply the division lemma to get
47 = 9 x 5 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 656 and 403 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(47,9) = HCF(103,47) = HCF(150,103) = HCF(253,150) = HCF(403,253) = HCF(656,403) .
