HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 823, 957 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 823, 957 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 823, 957 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 823, 957 is 1.
HCF(823, 957) = 1
HCF of 823, 957 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 823, 957 is 1.
Highest Common Factor of 823,957 is 1
Step 1: Since 957 > 823, we apply the division lemma to 957 and 823, to get
957 = 823 x 1 + 134
Step 2: Since the reminder 823 ≠ 0, we apply division lemma to 134 and 823, to get
823 = 134 x 6 + 19
Step 3: We consider the new divisor 134 and the new remainder 19, and apply the division lemma to get
134 = 19 x 7 + 1
We consider the new divisor 19 and the new remainder 1, and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 823 and 957 is 1
Notice that 1 = HCF(19,1) = HCF(134,19) = HCF(823,134) = HCF(957,823) .
