HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 449, 329, 312 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 449, 329, 312 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 449, 329, 312 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 449, 329, 312 is 1.
HCF(449, 329, 312) = 1
HCF of 449, 329, 312 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 449, 329, 312 is 1.
Highest Common Factor of 449,329,312 is 1
Step 1: Since 449 > 329, we apply the division lemma to 449 and 329, to get
449 = 329 x 1 + 120
Step 2: Since the reminder 329 ≠ 0, we apply division lemma to 120 and 329, to get
329 = 120 x 2 + 89
Step 3: We consider the new divisor 120 and the new remainder 89, and apply the division lemma to get
120 = 89 x 1 + 31
We consider the new divisor 89 and the new remainder 31,and apply the division lemma to get
89 = 31 x 2 + 27
We consider the new divisor 31 and the new remainder 27,and apply the division lemma to get
31 = 27 x 1 + 4
We consider the new divisor 27 and the new remainder 4,and apply the division lemma to get
27 = 4 x 6 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 449 and 329 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(27,4) = HCF(31,27) = HCF(89,31) = HCF(120,89) = HCF(329,120) = HCF(449,329) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 312 > 1, we apply the division lemma to 312 and 1, to get
312 = 1 x 312 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 312 is 1
Notice that 1 = HCF(312,1) .
