HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 296, 689, 61 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 296, 689, 61 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 296, 689, 61 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 296, 689, 61 is 1.
HCF(296, 689, 61) = 1
HCF of 296, 689, 61 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 296, 689, 61 is 1.
Highest Common Factor of 296,689,61 is 1
Step 1: Since 689 > 296, we apply the division lemma to 689 and 296, to get
689 = 296 x 2 + 97
Step 2: Since the reminder 296 ≠ 0, we apply division lemma to 97 and 296, to get
296 = 97 x 3 + 5
Step 3: We consider the new divisor 97 and the new remainder 5, and apply the division lemma to get
97 = 5 x 19 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 296 and 689 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(97,5) = HCF(296,97) = HCF(689,296) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61 > 1, we apply the division lemma to 61 and 1, to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 61 is 1
Notice that 1 = HCF(61,1) .
