HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 622, 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 622, 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 622, 349 is 1.

HCF(622, 349) = 1

Highest common factor (HCF) of 622, 349 is 1.

Highest Common Factor of 622,349 using Euclid's algorithm

Highest Common Factor of 622,349 is 1

Step 1: Since 622 > 349, we apply the division lemma to 622 and 349, to get

622 = 349 x 1 + 273

Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 273 and 349, to get

349 = 273 x 1 + 76

Step 3: We consider the new divisor 273 and the new remainder 76, and apply the division lemma to get

273 = 76 x 3 + 45

We consider the new divisor 76 and the new remainder 45,and apply the division lemma to get

76 = 45 x 1 + 31

We consider the new divisor 45 and the new remainder 31,and apply the division lemma to get

45 = 31 x 1 + 14

We consider the new divisor 31 and the new remainder 14,and apply the division lemma to get

31 = 14 x 2 + 3

We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get

14 = 3 x 4 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 622 and 349 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(31,14) = HCF(45,31) = HCF(76,45) = HCF(273,76) = HCF(349,273) = HCF(622,349) .
