HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 890, 621, 216 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 890, 621, 216 is 1 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 890, 621, 216 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 890, 621, 216 is 1.

HCF(890, 621, 216) = 1

HCF of 890, 621, 216 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 890, 621, 216 is 1.

Highest Common Factor of 890,621,216 using Euclid's algorithm

Highest Common Factor of 890,621,216 is 1

Step 1: Since 890 > 621, we apply the division lemma to 890 and 621, to get

890 = 621 x 1 + 269

Step 2: Since the reminder 621 ≠ 0, we apply division lemma to 269 and 621, to get

621 = 269 x 2 + 83

Step 3: We consider the new divisor 269 and the new remainder 83, and apply the division lemma to get

269 = 83 x 3 + 20

We consider the new divisor 83 and the new remainder 20,and apply the division lemma to get

83 = 20 x 4 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 890 and 621 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(83,20) = HCF(269,83) = HCF(621,269) = HCF(890,621) .

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

Step 1: Since 216 > 1, we apply the division lemma to 216 and 1, to get

216 = 1 x 216 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 216 is 1

Notice that 1 = HCF(216,1) .
