HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 23, 80, 739, 823 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 23, 80, 739, 823 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 23, 80, 739, 823 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 23, 80, 739, 823 is 1.
HCF(23, 80, 739, 823) = 1
HCF of 23, 80, 739, 823 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 23, 80, 739, 823 is 1.
Highest Common Factor of 23,80,739,823 is 1
Step 1: Since 80 > 23, we apply the division lemma to 80 and 23, to get
80 = 23 x 3 + 11
Step 2: Since the reminder 23 ≠ 0, we apply division lemma to 11 and 23, to get
23 = 11 x 2 + 1
Step 3: 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 23 and 80 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(80,23) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 739 > 1, we apply the division lemma to 739 and 1, to get
739 = 1 x 739 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 739 is 1
Notice that 1 = HCF(739,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 823 > 1, we apply the division lemma to 823 and 1, to get
823 = 1 x 823 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 823 is 1
Notice that 1 = HCF(823,1) .
