HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 100, 284, 207 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 100, 284, 207 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 100, 284, 207 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 100, 284, 207 is 1.

HCF(100, 284, 207) = 1

HCF of 100, 284, 207 using Euclid's algorithm

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

Highest common factor (HCF) of 100, 284, 207 is 1.

Highest Common Factor of 100,284,207 using Euclid's algorithm

Highest Common Factor of 100,284,207 is 1

Step 1: Since 284 > 100, we apply the division lemma to 284 and 100, to get

284 = 100 x 2 + 84

Step 2: Since the reminder 100 ≠ 0, we apply division lemma to 84 and 100, to get

100 = 84 x 1 + 16

Step 3: We consider the new divisor 84 and the new remainder 16, and apply the division lemma to get

84 = 16 x 5 + 4

We consider the new divisor 16 and the new remainder 4, and apply the division lemma to get

16 = 4 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 100 and 284 is 4

Notice that 4 = HCF(16,4) = HCF(84,16) = HCF(100,84) = HCF(284,100) .

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

Step 1: Since 207 > 4, we apply the division lemma to 207 and 4, to get

207 = 4 x 51 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 207 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(207,4) .
