HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 709, 920 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 709, 920 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, 920 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, 920 is 1.
HCF(709, 920) = 1
HCF of 709, 920 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, 920 is 1.
Highest Common Factor of 709,920 is 1
Step 1: Since 920 > 709, we apply the division lemma to 920 and 709, to get
920 = 709 x 1 + 211
Step 2: Since the reminder 709 ≠ 0, we apply division lemma to 211 and 709, to get
709 = 211 x 3 + 76
Step 3: We consider the new divisor 211 and the new remainder 76, and apply the division lemma to get
211 = 76 x 2 + 59
We consider the new divisor 76 and the new remainder 59,and apply the division lemma to get
76 = 59 x 1 + 17
We consider the new divisor 59 and the new remainder 17,and apply the division lemma to get
59 = 17 x 3 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 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 709 and 920 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(59,17) = HCF(76,59) = HCF(211,76) = HCF(709,211) = HCF(920,709) .
