HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 374, 997 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 845, 374, 997 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 845, 374, 997 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 845, 374, 997 is 1.
HCF(845, 374, 997) = 1
HCF of 845, 374, 997 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 845, 374, 997 is 1.
Highest Common Factor of 845,374,997 is 1
Step 1: Since 845 > 374, we apply the division lemma to 845 and 374, to get
845 = 374 x 2 + 97
Step 2: Since the reminder 374 ≠ 0, we apply division lemma to 97 and 374, to get
374 = 97 x 3 + 83
Step 3: We consider the new divisor 97 and the new remainder 83, and apply the division lemma to get
97 = 83 x 1 + 14
We consider the new divisor 83 and the new remainder 14,and apply the division lemma to get
83 = 14 x 5 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 845 and 374 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(83,14) = HCF(97,83) = HCF(374,97) = HCF(845,374) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 997 > 1, we apply the division lemma to 997 and 1, to get
997 = 1 x 997 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 997 is 1
Notice that 1 = HCF(997,1) .
