HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 771, 9717 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 771, 9717 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 771, 9717 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 771, 9717 is 3.
HCF(771, 9717) = 3
HCF of 771, 9717 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 771, 9717 is 3.
Highest Common Factor of 771,9717 is 3
Step 1: Since 9717 > 771, we apply the division lemma to 9717 and 771, to get
9717 = 771 x 12 + 465
Step 2: Since the reminder 771 ≠ 0, we apply division lemma to 465 and 771, to get
771 = 465 x 1 + 306
Step 3: We consider the new divisor 465 and the new remainder 306, and apply the division lemma to get
465 = 306 x 1 + 159
We consider the new divisor 306 and the new remainder 159,and apply the division lemma to get
306 = 159 x 1 + 147
We consider the new divisor 159 and the new remainder 147,and apply the division lemma to get
159 = 147 x 1 + 12
We consider the new divisor 147 and the new remainder 12,and apply the division lemma to get
147 = 12 x 12 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 771 and 9717 is 3
Notice that 3 = HCF(12,3) = HCF(147,12) = HCF(159,147) = HCF(306,159) = HCF(465,306) = HCF(771,465) = HCF(9717,771) .
