HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 813, 931, 125 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 813, 931, 125 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 813, 931, 125 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 813, 931, 125 is 1.
HCF(813, 931, 125) = 1
HCF of 813, 931, 125 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 813, 931, 125 is 1.
Highest Common Factor of 813,931,125 is 1
Step 1: Since 931 > 813, we apply the division lemma to 931 and 813, to get
931 = 813 x 1 + 118
Step 2: Since the reminder 813 ≠ 0, we apply division lemma to 118 and 813, to get
813 = 118 x 6 + 105
Step 3: We consider the new divisor 118 and the new remainder 105, and apply the division lemma to get
118 = 105 x 1 + 13
We consider the new divisor 105 and the new remainder 13,and apply the division lemma to get
105 = 13 x 8 + 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 813 and 931 is 1
Notice that 1 = HCF(13,1) = HCF(105,13) = HCF(118,105) = HCF(813,118) = HCF(931,813) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 125 > 1, we apply the division lemma to 125 and 1, to get
125 = 1 x 125 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 125 is 1
Notice that 1 = HCF(125,1) .
