HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 949, 349 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 949, 349 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 949, 349 is 1.

HCF(949, 349) = 1

Highest common factor (HCF) of 949, 349 is 1.

Highest Common Factor of 949,349 using Euclid's algorithm

Highest Common Factor of 949,349 is 1

Step 1: Since 949 > 349, we apply the division lemma to 949 and 349, to get

949 = 349 x 2 + 251

Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 251 and 349, to get

349 = 251 x 1 + 98

Step 3: We consider the new divisor 251 and the new remainder 98, and apply the division lemma to get

251 = 98 x 2 + 55

We consider the new divisor 98 and the new remainder 55,and apply the division lemma to get

98 = 55 x 1 + 43

We consider the new divisor 55 and the new remainder 43,and apply the division lemma to get

55 = 43 x 1 + 12

We consider the new divisor 43 and the new remainder 12,and apply the division lemma to get

43 = 12 x 3 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 949 and 349 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(43,12) = HCF(55,43) = HCF(98,55) = HCF(251,98) = HCF(349,251) = HCF(949,349) .
