HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 112, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 391, 112, 949 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 391, 112, 949 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 391, 112, 949 is 1.
HCF(391, 112, 949) = 1
HCF of 391, 112, 949 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 391, 112, 949 is 1.
Highest Common Factor of 391,112,949 is 1
Step 1: Since 391 > 112, we apply the division lemma to 391 and 112, to get
391 = 112 x 3 + 55
Step 2: Since the reminder 112 ≠ 0, we apply division lemma to 55 and 112, to get
112 = 55 x 2 + 2
Step 3: We consider the new divisor 55 and the new remainder 2, and apply the division lemma to get
55 = 2 x 27 + 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 391 and 112 is 1
Notice that 1 = HCF(2,1) = HCF(55,2) = HCF(112,55) = HCF(391,112) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 949 > 1, we apply the division lemma to 949 and 1, to get
949 = 1 x 949 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 949 is 1
Notice that 1 = HCF(949,1) .
