HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 805, 820, 892 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 805, 820, 892 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 805, 820, 892 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 805, 820, 892 is 1.
HCF(805, 820, 892) = 1
HCF of 805, 820, 892 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 805, 820, 892 is 1.
Highest Common Factor of 805,820,892 is 1
Step 1: Since 820 > 805, we apply the division lemma to 820 and 805, to get
820 = 805 x 1 + 15
Step 2: Since the reminder 805 ≠ 0, we apply division lemma to 15 and 805, to get
805 = 15 x 53 + 10
Step 3: We consider the new divisor 15 and the new remainder 10, and apply the division lemma to get
15 = 10 x 1 + 5
We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 805 and 820 is 5
Notice that 5 = HCF(10,5) = HCF(15,10) = HCF(805,15) = HCF(820,805) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 892 > 5, we apply the division lemma to 892 and 5, to get
892 = 5 x 178 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 1
Step 3: 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 5 and 892 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(892,5) .
