HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 491 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 949, 491 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 949, 491 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 949, 491 is 1.
HCF(949, 491) = 1
HCF of 949, 491 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 949, 491 is 1.
Highest Common Factor of 949,491 is 1
Step 1: Since 949 > 491, we apply the division lemma to 949 and 491, to get
949 = 491 x 1 + 458
Step 2: Since the reminder 491 ≠ 0, we apply division lemma to 458 and 491, to get
491 = 458 x 1 + 33
Step 3: We consider the new divisor 458 and the new remainder 33, and apply the division lemma to get
458 = 33 x 13 + 29
We consider the new divisor 33 and the new remainder 29,and apply the division lemma to get
33 = 29 x 1 + 4
We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get
29 = 4 x 7 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 491 is 1
Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(33,29) = HCF(458,33) = HCF(491,458) = HCF(949,491) .
