HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 343, 612 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 343, 612 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 343, 612 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 343, 612 is 1.

HCF(343, 612) = 1

Highest common factor (HCF) of 343, 612 is 1.

Highest Common Factor of 343,612 using Euclid's algorithm

Highest Common Factor of 343,612 is 1

Step 1: Since 612 > 343, we apply the division lemma to 612 and 343, to get

612 = 343 x 1 + 269

Step 2: Since the reminder 343 ≠ 0, we apply division lemma to 269 and 343, to get

343 = 269 x 1 + 74

Step 3: We consider the new divisor 269 and the new remainder 74, and apply the division lemma to get

269 = 74 x 3 + 47

We consider the new divisor 74 and the new remainder 47,and apply the division lemma to get

74 = 47 x 1 + 27

We consider the new divisor 47 and the new remainder 27,and apply the division lemma to get

47 = 27 x 1 + 20

We consider the new divisor 27 and the new remainder 20,and apply the division lemma to get

27 = 20 x 1 + 7

We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get

20 = 7 x 2 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 343 and 612 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(27,20) = HCF(47,27) = HCF(74,47) = HCF(269,74) = HCF(343,269) = HCF(612,343) .
