HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 630, 340, 682 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 630, 340, 682 is 2 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 630, 340, 682 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 630, 340, 682 is 2.
HCF(630, 340, 682) = 2
HCF of 630, 340, 682 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 630, 340, 682 is 2.
Highest Common Factor of 630,340,682 is 2
Step 1: Since 630 > 340, we apply the division lemma to 630 and 340, to get
630 = 340 x 1 + 290
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 290 and 340, to get
340 = 290 x 1 + 50
Step 3: We consider the new divisor 290 and the new remainder 50, and apply the division lemma to get
290 = 50 x 5 + 40
We consider the new divisor 50 and the new remainder 40,and apply the division lemma to get
50 = 40 x 1 + 10
We consider the new divisor 40 and the new remainder 10,and apply the division lemma to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 630 and 340 is 10
Notice that 10 = HCF(40,10) = HCF(50,40) = HCF(290,50) = HCF(340,290) = HCF(630,340) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 682 > 10, we apply the division lemma to 682 and 10, to get
682 = 10 x 68 + 2
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 2 and 10, to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 682 is 2
Notice that 2 = HCF(10,2) = HCF(682,10) .
