HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 686, 753 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 686, 753 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 686, 753 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 686, 753 is 1.
HCF(686, 753) = 1
HCF of 686, 753 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 686, 753 is 1.
Highest Common Factor of 686,753 is 1
Step 1: Since 753 > 686, we apply the division lemma to 753 and 686, to get
753 = 686 x 1 + 67
Step 2: Since the reminder 686 ≠ 0, we apply division lemma to 67 and 686, to get
686 = 67 x 10 + 16
Step 3: We consider the new divisor 67 and the new remainder 16, and apply the division lemma to get
67 = 16 x 4 + 3
We consider the new divisor 16 and the new remainder 3,and apply the division lemma to get
16 = 3 x 5 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 686 and 753 is 1
Notice that 1 = HCF(3,1) = HCF(16,3) = HCF(67,16) = HCF(686,67) = HCF(753,686) .
