HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 811, 669, 352, 17 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 811, 669, 352, 17 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 811, 669, 352, 17 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 811, 669, 352, 17 is 1.
HCF(811, 669, 352, 17) = 1
HCF of 811, 669, 352, 17 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 811, 669, 352, 17 is 1.
Highest Common Factor of 811,669,352,17 is 1
Step 1: Since 811 > 669, we apply the division lemma to 811 and 669, to get
811 = 669 x 1 + 142
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 142 and 669, to get
669 = 142 x 4 + 101
Step 3: We consider the new divisor 142 and the new remainder 101, and apply the division lemma to get
142 = 101 x 1 + 41
We consider the new divisor 101 and the new remainder 41,and apply the division lemma to get
101 = 41 x 2 + 19
We consider the new divisor 41 and the new remainder 19,and apply the division lemma to get
41 = 19 x 2 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 811 and 669 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(41,19) = HCF(101,41) = HCF(142,101) = HCF(669,142) = HCF(811,669) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 352 > 1, we apply the division lemma to 352 and 1, to get
352 = 1 x 352 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 352 is 1
Notice that 1 = HCF(352,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 17 > 1, we apply the division lemma to 17 and 1, to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 17 is 1
Notice that 1 = HCF(17,1) .
