HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 686, 499, 596 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 686, 499, 596 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, 499, 596 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, 499, 596 is 1.
HCF(686, 499, 596) = 1
HCF of 686, 499, 596 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, 499, 596 is 1.
Highest Common Factor of 686,499,596 is 1
Step 1: Since 686 > 499, we apply the division lemma to 686 and 499, to get
686 = 499 x 1 + 187
Step 2: Since the reminder 499 ≠ 0, we apply division lemma to 187 and 499, to get
499 = 187 x 2 + 125
Step 3: We consider the new divisor 187 and the new remainder 125, and apply the division lemma to get
187 = 125 x 1 + 62
We consider the new divisor 125 and the new remainder 62,and apply the division lemma to get
125 = 62 x 2 + 1
We consider the new divisor 62 and the new remainder 1,and apply the division lemma to get
62 = 1 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 686 and 499 is 1
Notice that 1 = HCF(62,1) = HCF(125,62) = HCF(187,125) = HCF(499,187) = HCF(686,499) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 596 > 1, we apply the division lemma to 596 and 1, to get
596 = 1 x 596 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 596 is 1
Notice that 1 = HCF(596,1) .
