HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 691, 9515, 1321 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 691, 9515, 1321 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 691, 9515, 1321 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 691, 9515, 1321 is 1.
HCF(691, 9515, 1321) = 1
HCF of 691, 9515, 1321 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 691, 9515, 1321 is 1.
Highest Common Factor of 691,9515,1321 is 1
Step 1: Since 9515 > 691, we apply the division lemma to 9515 and 691, to get
9515 = 691 x 13 + 532
Step 2: Since the reminder 691 ≠ 0, we apply division lemma to 532 and 691, to get
691 = 532 x 1 + 159
Step 3: We consider the new divisor 532 and the new remainder 159, and apply the division lemma to get
532 = 159 x 3 + 55
We consider the new divisor 159 and the new remainder 55,and apply the division lemma to get
159 = 55 x 2 + 49
We consider the new divisor 55 and the new remainder 49,and apply the division lemma to get
55 = 49 x 1 + 6
We consider the new divisor 49 and the new remainder 6,and apply the division lemma to get
49 = 6 x 8 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 691 and 9515 is 1
Notice that 1 = HCF(6,1) = HCF(49,6) = HCF(55,49) = HCF(159,55) = HCF(532,159) = HCF(691,532) = HCF(9515,691) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1321 > 1, we apply the division lemma to 1321 and 1, to get
1321 = 1 x 1321 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1321 is 1
Notice that 1 = HCF(1321,1) .
