HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 81, 23, 887, 712 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 81, 23, 887, 712 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 81, 23, 887, 712 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 81, 23, 887, 712 is 1.
HCF(81, 23, 887, 712) = 1
HCF of 81, 23, 887, 712 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 81, 23, 887, 712 is 1.
Highest Common Factor of 81,23,887,712 is 1
Step 1: Since 81 > 23, we apply the division lemma to 81 and 23, to get
81 = 23 x 3 + 12
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 12 and 23, to get
23 = 12 x 1 + 11
Step 3: We consider the new divisor 12 and the new remainder 11, and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1, and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 81 and 23 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(81,23) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 887 > 1, we apply the division lemma to 887 and 1, to get
887 = 1 x 887 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 887 is 1
Notice that 1 = HCF(887,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 712 > 1, we apply the division lemma to 712 and 1, to get
712 = 1 x 712 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 712 is 1
Notice that 1 = HCF(712,1) .
