HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 662, 970, 684 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 662, 970, 684 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 662, 970, 684 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 662, 970, 684 is 2.

HCF(662, 970, 684) = 2

## HCF of 662, 970, 684 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 662, 970, 684 is 2. ### Highest Common Factor of 662,970,684 is 2

Step 1: Since 970 > 662, we apply the division lemma to 970 and 662, to get

970 = 662 x 1 + 308

Step 2: Since the reminder 662 ≠ 0, we apply division lemma to 308 and 662, to get

662 = 308 x 2 + 46

Step 3: We consider the new divisor 308 and the new remainder 46, and apply the division lemma to get

308 = 46 x 6 + 32

We consider the new divisor 46 and the new remainder 32,and apply the division lemma to get

46 = 32 x 1 + 14

We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get

32 = 14 x 2 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 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 662 and 970 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(46,32) = HCF(308,46) = HCF(662,308) = HCF(970,662) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 684 > 2, we apply the division lemma to 684 and 2, to get

684 = 2 x 342 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 684 is 2

Notice that 2 = HCF(684,2) .
