HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 706, 434, 165 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 706, 434, 165 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 706, 434, 165 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 706, 434, 165 is 1.
HCF(706, 434, 165) = 1
HCF of 706, 434, 165 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 706, 434, 165 is 1.
Highest Common Factor of 706,434,165 is 1
Step 1: Since 706 > 434, we apply the division lemma to 706 and 434, to get
706 = 434 x 1 + 272
Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 272 and 434, to get
434 = 272 x 1 + 162
Step 3: We consider the new divisor 272 and the new remainder 162, and apply the division lemma to get
272 = 162 x 1 + 110
We consider the new divisor 162 and the new remainder 110,and apply the division lemma to get
162 = 110 x 1 + 52
We consider the new divisor 110 and the new remainder 52,and apply the division lemma to get
110 = 52 x 2 + 6
We consider the new divisor 52 and the new remainder 6,and apply the division lemma to get
52 = 6 x 8 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 706 and 434 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(52,6) = HCF(110,52) = HCF(162,110) = HCF(272,162) = HCF(434,272) = HCF(706,434) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 165 > 2, we apply the division lemma to 165 and 2, to get
165 = 2 x 82 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 165 is 1
Notice that 1 = HCF(2,1) = HCF(165,2) .
