HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 69657 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 970, 69657 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 970, 69657 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 970, 69657 is 1.
HCF(970, 69657) = 1
HCF of 970, 69657 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 970, 69657 is 1.
Highest Common Factor of 970,69657 is 1
Step 1: Since 69657 > 970, we apply the division lemma to 69657 and 970, to get
69657 = 970 x 71 + 787
Step 2: Since the reminder 970 ≠ 0, we apply division lemma to 787 and 970, to get
970 = 787 x 1 + 183
Step 3: We consider the new divisor 787 and the new remainder 183, and apply the division lemma to get
787 = 183 x 4 + 55
We consider the new divisor 183 and the new remainder 55,and apply the division lemma to get
183 = 55 x 3 + 18
We consider the new divisor 55 and the new remainder 18,and apply the division lemma to get
55 = 18 x 3 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 970 and 69657 is 1
Notice that 1 = HCF(18,1) = HCF(55,18) = HCF(183,55) = HCF(787,183) = HCF(970,787) = HCF(69657,970) .
