HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 449, 628 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 449, 628 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, 628 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, 628 is 1.
HCF(449, 628) = 1
HCF of 449, 628 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, 628 is 1.
Highest Common Factor of 449,628 is 1
Step 1: Since 628 > 449, we apply the division lemma to 628 and 449, to get
628 = 449 x 1 + 179
Step 2: Since the reminder 449 ≠ 0, we apply division lemma to 179 and 449, to get
449 = 179 x 2 + 91
Step 3: We consider the new divisor 179 and the new remainder 91, and apply the division lemma to get
179 = 91 x 1 + 88
We consider the new divisor 91 and the new remainder 88,and apply the division lemma to get
91 = 88 x 1 + 3
We consider the new divisor 88 and the new remainder 3,and apply the division lemma to get
88 = 3 x 29 + 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 628 is 1
Notice that 1 = HCF(3,1) = HCF(88,3) = HCF(91,88) = HCF(179,91) = HCF(449,179) = HCF(628,449) .
