HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 808, 771, 12 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 808, 771, 12 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 808, 771, 12 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 808, 771, 12 is 1.
HCF(808, 771, 12) = 1
HCF of 808, 771, 12 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 808, 771, 12 is 1.
Highest Common Factor of 808,771,12 is 1
Step 1: Since 808 > 771, we apply the division lemma to 808 and 771, to get
808 = 771 x 1 + 37
Step 2: Since the reminder 771 ≠ 0, we apply division lemma to 37 and 771, to get
771 = 37 x 20 + 31
Step 3: We consider the new divisor 37 and the new remainder 31, and apply the division lemma to get
37 = 31 x 1 + 6
We consider the new divisor 31 and the new remainder 6,and apply the division lemma to get
31 = 6 x 5 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 808 and 771 is 1
Notice that 1 = HCF(6,1) = HCF(31,6) = HCF(37,31) = HCF(771,37) = HCF(808,771) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 12 > 1, we apply the division lemma to 12 and 1, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 12 is 1
Notice that 1 = HCF(12,1) .
