HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 3077 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 3077 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 819, 3077 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 819, 3077 is 1.
HCF(819, 3077) = 1
HCF of 819, 3077 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 819, 3077 is 1.
Highest Common Factor of 819,3077 is 1
Step 1: Since 3077 > 819, we apply the division lemma to 3077 and 819, to get
3077 = 819 x 3 + 620
Step 2: Since the reminder 819 ≠ 0, we apply division lemma to 620 and 819, to get
819 = 620 x 1 + 199
Step 3: We consider the new divisor 620 and the new remainder 199, and apply the division lemma to get
620 = 199 x 3 + 23
We consider the new divisor 199 and the new remainder 23,and apply the division lemma to get
199 = 23 x 8 + 15
We consider the new divisor 23 and the new remainder 15,and apply the division lemma to get
23 = 15 x 1 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 819 and 3077 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(23,15) = HCF(199,23) = HCF(620,199) = HCF(819,620) = HCF(3077,819) .
