HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 839, 923, 353, 81 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 839, 923, 353, 81 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, 923, 353, 81 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, 923, 353, 81 is 1.
HCF(839, 923, 353, 81) = 1
HCF of 839, 923, 353, 81 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 839, 923, 353, 81 is 1.
Highest Common Factor of 839,923,353,81 is 1
Step 1: Since 923 > 839, we apply the division lemma to 923 and 839, to get
923 = 839 x 1 + 84
Step 2: Since the reminder 839 ≠ 0, we apply division lemma to 84 and 839, to get
839 = 84 x 9 + 83
Step 3: We consider the new divisor 84 and the new remainder 83, and apply the division lemma to get
84 = 83 x 1 + 1
We consider the new divisor 83 and the new remainder 1, and apply the division lemma to get
83 = 1 x 83 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 839 and 923 is 1
Notice that 1 = HCF(83,1) = HCF(84,83) = HCF(839,84) = HCF(923,839) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 353 > 1, we apply the division lemma to 353 and 1, to get
353 = 1 x 353 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 353 is 1
Notice that 1 = HCF(353,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 81 > 1, we apply the division lemma to 81 and 1, to get
81 = 1 x 81 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 81 is 1
Notice that 1 = HCF(81,1) .
