HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 12, 840, 890 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 12, 840, 890 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 12, 840, 890 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 12, 840, 890 is 2.

HCF(12, 840, 890) = 2

HCF of 12, 840, 890 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 12, 840, 890 is 2.

Highest Common Factor of 12,840,890 using Euclid's algorithm

Highest Common Factor of 12,840,890 is 2

Step 1: Since 840 > 12, we apply the division lemma to 840 and 12, to get

840 = 12 x 70 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 12 and 840 is 12

Notice that 12 = HCF(840,12) .


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

Step 1: Since 890 > 12, we apply the division lemma to 890 and 12, to get

890 = 12 x 74 + 2

Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 2 and 12, to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 12 and 890 is 2

Notice that 2 = HCF(12,2) = HCF(890,12) .
