HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 646, 906 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 869, 646, 906 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 869, 646, 906 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 869, 646, 906 is 1.

HCF(869, 646, 906) = 1

Highest common factor (HCF) of 869, 646, 906 is 1.

Highest Common Factor of 869,646,906 using Euclid's algorithm

Highest Common Factor of 869,646,906 is 1

Step 1: Since 869 > 646, we apply the division lemma to 869 and 646, to get

869 = 646 x 1 + 223

Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 223 and 646, to get

646 = 223 x 2 + 200

Step 3: We consider the new divisor 223 and the new remainder 200, and apply the division lemma to get

223 = 200 x 1 + 23

We consider the new divisor 200 and the new remainder 23,and apply the division lemma to get

200 = 23 x 8 + 16

We consider the new divisor 23 and the new remainder 16,and apply the division lemma to get

23 = 16 x 1 + 7

We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get

16 = 7 x 2 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 869 and 646 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(23,16) = HCF(200,23) = HCF(223,200) = HCF(646,223) = HCF(869,646) .

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

Step 1: Since 906 > 1, we apply the division lemma to 906 and 1, to get

906 = 1 x 906 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 906 is 1

Notice that 1 = HCF(906,1) .
