HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 957, 7197 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 957, 7197 is 3 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 957, 7197 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 957, 7197 is 3.
HCF(957, 7197) = 3
HCF of 957, 7197 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 957, 7197 is 3.
Highest Common Factor of 957,7197 is 3
Step 1: Since 7197 > 957, we apply the division lemma to 7197 and 957, to get
7197 = 957 x 7 + 498
Step 2: Since the reminder 957 ≠ 0, we apply division lemma to 498 and 957, to get
957 = 498 x 1 + 459
Step 3: We consider the new divisor 498 and the new remainder 459, and apply the division lemma to get
498 = 459 x 1 + 39
We consider the new divisor 459 and the new remainder 39,and apply the division lemma to get
459 = 39 x 11 + 30
We consider the new divisor 39 and the new remainder 30,and apply the division lemma to get
39 = 30 x 1 + 9
We consider the new divisor 30 and the new remainder 9,and apply the division lemma to get
30 = 9 x 3 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 957 and 7197 is 3
Notice that 3 = HCF(9,3) = HCF(30,9) = HCF(39,30) = HCF(459,39) = HCF(498,459) = HCF(957,498) = HCF(7197,957) .
