HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 261, 715, 831 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 261, 715, 831 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 261, 715, 831 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 261, 715, 831 is 1.
HCF(261, 715, 831) = 1
HCF of 261, 715, 831 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 261, 715, 831 is 1.
Highest Common Factor of 261,715,831 is 1
Step 1: Since 715 > 261, we apply the division lemma to 715 and 261, to get
715 = 261 x 2 + 193
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 193 and 261, to get
261 = 193 x 1 + 68
Step 3: We consider the new divisor 193 and the new remainder 68, and apply the division lemma to get
193 = 68 x 2 + 57
We consider the new divisor 68 and the new remainder 57,and apply the division lemma to get
68 = 57 x 1 + 11
We consider the new divisor 57 and the new remainder 11,and apply the division lemma to get
57 = 11 x 5 + 2
We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get
11 = 2 x 5 + 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 261 and 715 is 1
Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(57,11) = HCF(68,57) = HCF(193,68) = HCF(261,193) = HCF(715,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 831 > 1, we apply the division lemma to 831 and 1, to get
831 = 1 x 831 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 831 is 1
Notice that 1 = HCF(831,1) .
