HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 856, 330, 640 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 856, 330, 640 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 856, 330, 640 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 856, 330, 640 is 2.

HCF(856, 330, 640) = 2

HCF of 856, 330, 640 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 856, 330, 640 is 2.

Highest Common Factor of 856,330,640 using Euclid's algorithm

Highest Common Factor of 856,330,640 is 2

Step 1: Since 856 > 330, we apply the division lemma to 856 and 330, to get

856 = 330 x 2 + 196

Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 196 and 330, to get

330 = 196 x 1 + 134

Step 3: We consider the new divisor 196 and the new remainder 134, and apply the division lemma to get

196 = 134 x 1 + 62

We consider the new divisor 134 and the new remainder 62,and apply the division lemma to get

134 = 62 x 2 + 10

We consider the new divisor 62 and the new remainder 10,and apply the division lemma to get

62 = 10 x 6 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 856 and 330 is 2

Notice that 2 = HCF(10,2) = HCF(62,10) = HCF(134,62) = HCF(196,134) = HCF(330,196) = HCF(856,330) .


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

Step 1: Since 640 > 2, we apply the division lemma to 640 and 2, to get

640 = 2 x 320 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 640 is 2

Notice that 2 = HCF(640,2) .
