HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 359, 469, 169 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 359, 469, 169 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 359, 469, 169 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 359, 469, 169 is 1.
HCF(359, 469, 169) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 359, 469, 169 is 1.
Step 1: Since 469 > 359, we apply the division lemma to 469 and 359, to get
469 = 359 x 1 + 110
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 110 and 359, to get
359 = 110 x 3 + 29
Step 3: We consider the new divisor 110 and the new remainder 29, and apply the division lemma to get
110 = 29 x 3 + 23
We consider the new divisor 29 and the new remainder 23,and apply the division lemma to get
29 = 23 x 1 + 6
We consider the new divisor 23 and the new remainder 6,and apply the division lemma to get
23 = 6 x 3 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 359 and 469 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(23,6) = HCF(29,23) = HCF(110,29) = HCF(359,110) = HCF(469,359) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 169 > 1, we apply the division lemma to 169 and 1, to get
169 = 1 x 169 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 169 is 1
Notice that 1 = HCF(169,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
