HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 4693 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 685, 4693 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, 4693 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, 4693 is 1.
HCF(685, 4693) = 1
HCF of 685, 4693 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, 4693 is 1.
Highest Common Factor of 685,4693 is 1
Step 1: Since 4693 > 685, we apply the division lemma to 4693 and 685, to get
4693 = 685 x 6 + 583
Step 2: Since the reminder 685 ≠ 0, we apply division lemma to 583 and 685, to get
685 = 583 x 1 + 102
Step 3: We consider the new divisor 583 and the new remainder 102, and apply the division lemma to get
583 = 102 x 5 + 73
We consider the new divisor 102 and the new remainder 73,and apply the division lemma to get
102 = 73 x 1 + 29
We consider the new divisor 73 and the new remainder 29,and apply the division lemma to get
73 = 29 x 2 + 15
We consider the new divisor 29 and the new remainder 15,and apply the division lemma to get
29 = 15 x 1 + 14
We consider the new divisor 15 and the new remainder 14,and apply the division lemma to get
15 = 14 x 1 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 685 and 4693 is 1
Notice that 1 = HCF(14,1) = HCF(15,14) = HCF(29,15) = HCF(73,29) = HCF(102,73) = HCF(583,102) = HCF(685,583) = HCF(4693,685) .
