HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 7773, 6364 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 7773, 6364 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 831, 7773, 6364 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 831, 7773, 6364 is 1.
HCF(831, 7773, 6364) = 1
HCF of 831, 7773, 6364 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 831, 7773, 6364 is 1.
Highest Common Factor of 831,7773,6364 is 1
Step 1: Since 7773 > 831, we apply the division lemma to 7773 and 831, to get
7773 = 831 x 9 + 294
Step 2: Since the reminder 831 ≠ 0, we apply division lemma to 294 and 831, to get
831 = 294 x 2 + 243
Step 3: We consider the new divisor 294 and the new remainder 243, and apply the division lemma to get
294 = 243 x 1 + 51
We consider the new divisor 243 and the new remainder 51,and apply the division lemma to get
243 = 51 x 4 + 39
We consider the new divisor 51 and the new remainder 39,and apply the division lemma to get
51 = 39 x 1 + 12
We consider the new divisor 39 and the new remainder 12,and apply the division lemma to get
39 = 12 x 3 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 831 and 7773 is 3
Notice that 3 = HCF(12,3) = HCF(39,12) = HCF(51,39) = HCF(243,51) = HCF(294,243) = HCF(831,294) = HCF(7773,831) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 6364 > 3, we apply the division lemma to 6364 and 3, to get
6364 = 3 x 2121 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 6364 is 1
Notice that 1 = HCF(3,1) = HCF(6364,3) .
