HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 97, 557, 805 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 97, 557, 805 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 97, 557, 805 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 97, 557, 805 is 1.
HCF(97, 557, 805) = 1
HCF of 97, 557, 805 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 97, 557, 805 is 1.
Highest Common Factor of 97,557,805 is 1
Step 1: Since 557 > 97, we apply the division lemma to 557 and 97, to get
557 = 97 x 5 + 72
Step 2: Since the reminder 97 ≠ 0, we apply division lemma to 72 and 97, to get
97 = 72 x 1 + 25
Step 3: We consider the new divisor 72 and the new remainder 25, and apply the division lemma to get
72 = 25 x 2 + 22
We consider the new divisor 25 and the new remainder 22,and apply the division lemma to get
25 = 22 x 1 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 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 97 and 557 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(72,25) = HCF(97,72) = HCF(557,97) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 805 > 1, we apply the division lemma to 805 and 1, to get
805 = 1 x 805 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 805 is 1
Notice that 1 = HCF(805,1) .
