HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 819, 532, 346 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 819, 532, 346 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, 532, 346 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, 532, 346 is 1.
HCF(819, 532, 346) = 1
HCF of 819, 532, 346 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, 532, 346 is 1.
Highest Common Factor of 819,532,346 is 1
Step 1: Since 819 > 532, we apply the division lemma to 819 and 532, to get
819 = 532 x 1 + 287
Step 2: Since the reminder 532 ≠ 0, we apply division lemma to 287 and 532, to get
532 = 287 x 1 + 245
Step 3: We consider the new divisor 287 and the new remainder 245, and apply the division lemma to get
287 = 245 x 1 + 42
We consider the new divisor 245 and the new remainder 42,and apply the division lemma to get
245 = 42 x 5 + 35
We consider the new divisor 42 and the new remainder 35,and apply the division lemma to get
42 = 35 x 1 + 7
We consider the new divisor 35 and the new remainder 7,and apply the division lemma to get
35 = 7 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 819 and 532 is 7
Notice that 7 = HCF(35,7) = HCF(42,35) = HCF(245,42) = HCF(287,245) = HCF(532,287) = HCF(819,532) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 346 > 7, we apply the division lemma to 346 and 7, to get
346 = 7 x 49 + 3
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 3 and 7, to get
7 = 3 x 2 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 7 and 346 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(346,7) .
