HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 400, 682 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 400, 682 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 400, 682 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 400, 682 is 2.

HCF(400, 682) = 2

Highest common factor (HCF) of 400, 682 is 2.

Highest Common Factor of 400,682 using Euclid's algorithm

Highest Common Factor of 400,682 is 2

Step 1: Since 682 > 400, we apply the division lemma to 682 and 400, to get

682 = 400 x 1 + 282

Step 2: Since the reminder 400 ≠ 0, we apply division lemma to 282 and 400, to get

400 = 282 x 1 + 118

Step 3: We consider the new divisor 282 and the new remainder 118, and apply the division lemma to get

282 = 118 x 2 + 46

We consider the new divisor 118 and the new remainder 46,and apply the division lemma to get

118 = 46 x 2 + 26

We consider the new divisor 46 and the new remainder 26,and apply the division lemma to get

46 = 26 x 1 + 20

We consider the new divisor 26 and the new remainder 20,and apply the division lemma to get

26 = 20 x 1 + 6

We consider the new divisor 20 and the new remainder 6,and apply the division lemma to get

20 = 6 x 3 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 400 and 682 is 2

Notice that 2 = HCF(6,2) = HCF(20,6) = HCF(26,20) = HCF(46,26) = HCF(118,46) = HCF(282,118) = HCF(400,282) = HCF(682,400) .
