HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 804, 698 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 804, 698 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 804, 698 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 804, 698 is 2.

HCF(804, 698) = 2

Highest common factor (HCF) of 804, 698 is 2.

Highest Common Factor of 804,698 using Euclid's algorithm

Highest Common Factor of 804,698 is 2

Step 1: Since 804 > 698, we apply the division lemma to 804 and 698, to get

804 = 698 x 1 + 106

Step 2: Since the reminder 698 ≠ 0, we apply division lemma to 106 and 698, to get

698 = 106 x 6 + 62

Step 3: We consider the new divisor 106 and the new remainder 62, and apply the division lemma to get

106 = 62 x 1 + 44

We consider the new divisor 62 and the new remainder 44,and apply the division lemma to get

62 = 44 x 1 + 18

We consider the new divisor 44 and the new remainder 18,and apply the division lemma to get

44 = 18 x 2 + 8

We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get

18 = 8 x 2 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 804 and 698 is 2

Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(44,18) = HCF(62,44) = HCF(106,62) = HCF(698,106) = HCF(804,698) .
