HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 689, 296, 281 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 689, 296, 281 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 689, 296, 281 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 689, 296, 281 is 1.
HCF(689, 296, 281) = 1
HCF of 689, 296, 281 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 689, 296, 281 is 1.
Highest Common Factor of 689,296,281 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 689 and 296 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 281 > 1, we apply the division lemma to 281 and 1, to get
281 = 1 x 281 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 281 is 1
Notice that 1 = HCF(281,1) .
