HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 729, 839, 178, 165 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 729, 839, 178, 165 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 729, 839, 178, 165 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 729, 839, 178, 165 is 1.
HCF(729, 839, 178, 165) = 1
HCF of 729, 839, 178, 165 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 729, 839, 178, 165 is 1.
Highest Common Factor of 729,839,178,165 is 1
Step 1: Since 839 > 729, we apply the division lemma to 839 and 729, to get
839 = 729 x 1 + 110
Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 110 and 729, to get
729 = 110 x 6 + 69
Step 3: We consider the new divisor 110 and the new remainder 69, and apply the division lemma to get
110 = 69 x 1 + 41
We consider the new divisor 69 and the new remainder 41,and apply the division lemma to get
69 = 41 x 1 + 28
We consider the new divisor 41 and the new remainder 28,and apply the division lemma to get
41 = 28 x 1 + 13
We consider the new divisor 28 and the new remainder 13,and apply the division lemma to get
28 = 13 x 2 + 2
We consider the new divisor 13 and the new remainder 2,and apply the division lemma to get
13 = 2 x 6 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 729 and 839 is 1
Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(28,13) = HCF(41,28) = HCF(69,41) = HCF(110,69) = HCF(729,110) = HCF(839,729) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 178 > 1, we apply the division lemma to 178 and 1, to get
178 = 1 x 178 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 178 is 1
Notice that 1 = HCF(178,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 165 > 1, we apply the division lemma to 165 and 1, to get
165 = 1 x 165 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 165 is 1
Notice that 1 = HCF(165,1) .
