HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 994, 634 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 994, 634 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 994, 634 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 994, 634 is 2.

HCF(994, 634) = 2

Highest common factor (HCF) of 994, 634 is 2.

Highest Common Factor of 994,634 using Euclid's algorithm

Highest Common Factor of 994,634 is 2

Step 1: Since 994 > 634, we apply the division lemma to 994 and 634, to get

994 = 634 x 1 + 360

Step 2: Since the reminder 634 ≠ 0, we apply division lemma to 360 and 634, to get

634 = 360 x 1 + 274

Step 3: We consider the new divisor 360 and the new remainder 274, and apply the division lemma to get

360 = 274 x 1 + 86

We consider the new divisor 274 and the new remainder 86,and apply the division lemma to get

274 = 86 x 3 + 16

We consider the new divisor 86 and the new remainder 16,and apply the division lemma to get

86 = 16 x 5 + 6

We consider the new divisor 16 and the new remainder 6,and apply the division lemma to get

16 = 6 x 2 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 994 and 634 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(16,6) = HCF(86,16) = HCF(274,86) = HCF(360,274) = HCF(634,360) = HCF(994,634) .
