HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 709, 981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 709, 981 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 709, 981 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 709, 981 is 1.
HCF(709, 981) = 1
HCF of 709, 981 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 709, 981 is 1.
Highest Common Factor of 709,981 is 1
Step 1: Since 981 > 709, we apply the division lemma to 981 and 709, to get
981 = 709 x 1 + 272
Step 2: Since the reminder 709 ≠ 0, we apply division lemma to 272 and 709, to get
709 = 272 x 2 + 165
Step 3: We consider the new divisor 272 and the new remainder 165, and apply the division lemma to get
272 = 165 x 1 + 107
We consider the new divisor 165 and the new remainder 107,and apply the division lemma to get
165 = 107 x 1 + 58
We consider the new divisor 107 and the new remainder 58,and apply the division lemma to get
107 = 58 x 1 + 49
We consider the new divisor 58 and the new remainder 49,and apply the division lemma to get
58 = 49 x 1 + 9
We consider the new divisor 49 and the new remainder 9,and apply the division lemma to get
49 = 9 x 5 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 709 and 981 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(49,9) = HCF(58,49) = HCF(107,58) = HCF(165,107) = HCF(272,165) = HCF(709,272) = HCF(981,709) .
