HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 689, 613 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 689, 613 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 493, 689, 613 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 493, 689, 613 is 1.
HCF(493, 689, 613) = 1
HCF of 493, 689, 613 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 689, 613 is 1.
Highest Common Factor of 493,689,613 is 1
Step 1: Since 689 > 493, we apply the division lemma to 689 and 493, to get
689 = 493 x 1 + 196
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 196 and 493, to get
493 = 196 x 2 + 101
Step 3: We consider the new divisor 196 and the new remainder 101, and apply the division lemma to get
196 = 101 x 1 + 95
We consider the new divisor 101 and the new remainder 95,and apply the division lemma to get
101 = 95 x 1 + 6
We consider the new divisor 95 and the new remainder 6,and apply the division lemma to get
95 = 6 x 15 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 493 and 689 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(95,6) = HCF(101,95) = HCF(196,101) = HCF(493,196) = HCF(689,493) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 613 > 1, we apply the division lemma to 613 and 1, to get
613 = 1 x 613 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 613 is 1
Notice that 1 = HCF(613,1) .
