HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 684, 994 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 684, 994 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 684, 994 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 684, 994 is 2.

HCF(684, 994) = 2

Highest Common Factor of 684,994 using Euclid's algorithm

Highest Common Factor of 684,994 is 2

Step 1: Since 994 > 684, we apply the division lemma to 994 and 684, to get

994 = 684 x 1 + 310

Step 2: Since the reminder 684 ≠ 0, we apply division lemma to 310 and 684, to get

684 = 310 x 2 + 64

Step 3: We consider the new divisor 310 and the new remainder 64, and apply the division lemma to get

310 = 64 x 4 + 54

We consider the new divisor 64 and the new remainder 54,and apply the division lemma to get

64 = 54 x 1 + 10

We consider the new divisor 54 and the new remainder 10,and apply the division lemma to get

54 = 10 x 5 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 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 684 and 994 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(54,10) = HCF(64,54) = HCF(310,64) = HCF(684,310) = HCF(994,684) .
