HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 873, 874, 821 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 873, 874, 821 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 873, 874, 821 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 873, 874, 821 is 1.
HCF(873, 874, 821) = 1
HCF of 873, 874, 821 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 873, 874, 821 is 1.
Highest Common Factor of 873,874,821 is 1
Step 1: Since 874 > 873, we apply the division lemma to 874 and 873, to get
874 = 873 x 1 + 1
Step 2: Since the reminder 873 ≠ 0, we apply division lemma to 1 and 873, to get
873 = 1 x 873 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 873 and 874 is 1
Notice that 1 = HCF(873,1) = HCF(874,873) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 821 > 1, we apply the division lemma to 821 and 1, to get
821 = 1 x 821 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 821 is 1
Notice that 1 = HCF(821,1) .
