HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 669, 611 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 669, 611 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 797, 669, 611 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 797, 669, 611 is 1.
HCF(797, 669, 611) = 1
HCF of 797, 669, 611 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 669, 611 is 1.
Highest Common Factor of 797,669,611 is 1
Step 1: Since 797 > 669, we apply the division lemma to 797 and 669, to get
797 = 669 x 1 + 128
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 128 and 669, to get
669 = 128 x 5 + 29
Step 3: We consider the new divisor 128 and the new remainder 29, and apply the division lemma to get
128 = 29 x 4 + 12
We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get
29 = 12 x 2 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 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 797 and 669 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(128,29) = HCF(669,128) = HCF(797,669) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 611 > 1, we apply the division lemma to 611 and 1, to get
611 = 1 x 611 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 611 is 1
Notice that 1 = HCF(611,1) .
