HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 8044 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 685, 8044 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 685, 8044 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 685, 8044 is 1.
HCF(685, 8044) = 1
HCF of 685, 8044 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 685, 8044 is 1.
Highest Common Factor of 685,8044 is 1
Step 1: Since 8044 > 685, we apply the division lemma to 8044 and 685, to get
8044 = 685 x 11 + 509
Step 2: Since the reminder 685 ≠ 0, we apply division lemma to 509 and 685, to get
685 = 509 x 1 + 176
Step 3: We consider the new divisor 509 and the new remainder 176, and apply the division lemma to get
509 = 176 x 2 + 157
We consider the new divisor 176 and the new remainder 157,and apply the division lemma to get
176 = 157 x 1 + 19
We consider the new divisor 157 and the new remainder 19,and apply the division lemma to get
157 = 19 x 8 + 5
We consider the new divisor 19 and the new remainder 5,and apply the division lemma to get
19 = 5 x 3 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 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 685 and 8044 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(19,5) = HCF(157,19) = HCF(176,157) = HCF(509,176) = HCF(685,509) = HCF(8044,685) .
