HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 797, 890, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 797, 890, 91 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 797, 890, 91 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 797, 890, 91 is 1.
HCF(797, 890, 91) = 1
HCF of 797, 890, 91 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 797, 890, 91 is 1.
Highest Common Factor of 797,890,91 is 1
Step 1: Since 890 > 797, we apply the division lemma to 890 and 797, to get
890 = 797 x 1 + 93
Step 2: Since the reminder 797 ≠ 0, we apply division lemma to 93 and 797, to get
797 = 93 x 8 + 53
Step 3: We consider the new divisor 93 and the new remainder 53, and apply the division lemma to get
93 = 53 x 1 + 40
We consider the new divisor 53 and the new remainder 40,and apply the division lemma to get
53 = 40 x 1 + 13
We consider the new divisor 40 and the new remainder 13,and apply the division lemma to get
40 = 13 x 3 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 797 and 890 is 1
Notice that 1 = HCF(13,1) = HCF(40,13) = HCF(53,40) = HCF(93,53) = HCF(797,93) = HCF(890,797) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 1, we apply the division lemma to 91 and 1, to get
91 = 1 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91 is 1
Notice that 1 = HCF(91,1) .
