HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 749, 449 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 749, 449 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 749, 449 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 749, 449 is 1.
HCF(749, 449) = 1
HCF of 749, 449 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 749, 449 is 1.
Highest Common Factor of 749,449 is 1
Step 1: Since 749 > 449, we apply the division lemma to 749 and 449, to get
749 = 449 x 1 + 300
Step 2: Since the reminder 449 ≠ 0, we apply division lemma to 300 and 449, to get
449 = 300 x 1 + 149
Step 3: We consider the new divisor 300 and the new remainder 149, and apply the division lemma to get
300 = 149 x 2 + 2
We consider the new divisor 149 and the new remainder 2,and apply the division lemma to get
149 = 2 x 74 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 749 and 449 is 1
Notice that 1 = HCF(2,1) = HCF(149,2) = HCF(300,149) = HCF(449,300) = HCF(749,449) .
