HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 897, 115, 31 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 897, 115, 31 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 897, 115, 31 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 897, 115, 31 is 1.
HCF(897, 115, 31) = 1
HCF of 897, 115, 31 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 897, 115, 31 is 1.
Highest Common Factor of 897,115,31 is 1
Step 1: Since 897 > 115, we apply the division lemma to 897 and 115, to get
897 = 115 x 7 + 92
Step 2: Since the reminder 115 ≠ 0, we apply division lemma to 92 and 115, to get
115 = 92 x 1 + 23
Step 3: We consider the new divisor 92 and the new remainder 23, and apply the division lemma to get
92 = 23 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 897 and 115 is 23
Notice that 23 = HCF(92,23) = HCF(115,92) = HCF(897,115) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 31 > 23, we apply the division lemma to 31 and 23, to get
31 = 23 x 1 + 8
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 8 and 23, to get
23 = 8 x 2 + 7
Step 3: We consider the new divisor 8 and the new remainder 7, and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1, and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 23 and 31 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) .
