HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 208, 797 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 858, 208, 797 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 858, 208, 797 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 858, 208, 797 is 1.
HCF(858, 208, 797) = 1
HCF of 858, 208, 797 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 858, 208, 797 is 1.
Highest Common Factor of 858,208,797 is 1
Step 1: Since 858 > 208, we apply the division lemma to 858 and 208, to get
858 = 208 x 4 + 26
Step 2: Since the reminder 208 ≠ 0, we apply division lemma to 26 and 208, to get
208 = 26 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 858 and 208 is 26
Notice that 26 = HCF(208,26) = HCF(858,208) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 797 > 26, we apply the division lemma to 797 and 26, to get
797 = 26 x 30 + 17
Step 2: Since the reminder 26 ≠ 0, we apply division lemma to 17 and 26, to get
26 = 17 x 1 + 9
Step 3: We consider the new divisor 17 and the new remainder 9, and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 26 and 797 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(797,26) .
