HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 686, 514, 713 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 686, 514, 713 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, 514, 713 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, 514, 713 is 1.
HCF(686, 514, 713) = 1
HCF of 686, 514, 713 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, 514, 713 is 1.
Highest Common Factor of 686,514,713 is 1
Step 1: Since 686 > 514, we apply the division lemma to 686 and 514, to get
686 = 514 x 1 + 172
Step 2: Since the reminder 514 ≠ 0, we apply division lemma to 172 and 514, to get
514 = 172 x 2 + 170
Step 3: We consider the new divisor 172 and the new remainder 170, and apply the division lemma to get
172 = 170 x 1 + 2
We consider the new divisor 170 and the new remainder 2, and apply the division lemma to get
170 = 2 x 85 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 686 and 514 is 2
Notice that 2 = HCF(170,2) = HCF(172,170) = HCF(514,172) = HCF(686,514) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 713 > 2, we apply the division lemma to 713 and 2, to get
713 = 2 x 356 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 713 is 1
Notice that 1 = HCF(2,1) = HCF(713,2) .
