HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 839, 502, 729, 61 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 839, 502, 729, 61 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 839, 502, 729, 61 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 839, 502, 729, 61 is 1.
HCF(839, 502, 729, 61) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 839, 502, 729, 61 is 1.
Step 1: Since 839 > 502, we apply the division lemma to 839 and 502, to get
839 = 502 x 1 + 337
Step 2: Since the reminder 502 ≠ 0, we apply division lemma to 337 and 502, to get
502 = 337 x 1 + 165
Step 3: We consider the new divisor 337 and the new remainder 165, and apply the division lemma to get
337 = 165 x 2 + 7
We consider the new divisor 165 and the new remainder 7,and apply the division lemma to get
165 = 7 x 23 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
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 839 and 502 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(165,7) = HCF(337,165) = HCF(502,337) = HCF(839,502) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 729 > 1, we apply the division lemma to 729 and 1, to get
729 = 1 x 729 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 729 is 1
Notice that 1 = HCF(729,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61 > 1, we apply the division lemma to 61 and 1, to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 61 is 1
Notice that 1 = HCF(61,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
