HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 297, 867, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 297, 867, 70 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 297, 867, 70 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 297, 867, 70 is 1.

HCF(297, 867, 70) = 1

Highest common factor (HCF) of 297, 867, 70 is 1.

Highest Common Factor of 297,867,70 using Euclid's algorithm

Highest Common Factor of 297,867,70 is 1

Step 1: Since 867 > 297, we apply the division lemma to 867 and 297, to get

867 = 297 x 2 + 273

Step 2: Since the reminder 297 ≠ 0, we apply division lemma to 273 and 297, to get

297 = 273 x 1 + 24

Step 3: We consider the new divisor 273 and the new remainder 24, and apply the division lemma to get

273 = 24 x 11 + 9

We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get

24 = 9 x 2 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 297 and 867 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(273,24) = HCF(297,273) = HCF(867,297) .

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

Step 1: Since 70 > 3, we apply the division lemma to 70 and 3, to get

70 = 3 x 23 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 70 is 1

Notice that 1 = HCF(3,1) = HCF(70,3) .
