HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 208, 924 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 869, 208, 924 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, 208, 924 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, 208, 924 is 1.

HCF(869, 208, 924) = 1

Highest common factor (HCF) of 869, 208, 924 is 1.

Highest Common Factor of 869,208,924 using Euclid's algorithm

Highest Common Factor of 869,208,924 is 1

Step 1: Since 869 > 208, we apply the division lemma to 869 and 208, to get

869 = 208 x 4 + 37

Step 2: Since the reminder 208 ≠ 0, we apply division lemma to 37 and 208, to get

208 = 37 x 5 + 23

Step 3: We consider the new divisor 37 and the new remainder 23, and apply the division lemma to get

37 = 23 x 1 + 14

We consider the new divisor 23 and the new remainder 14,and apply the division lemma to get

23 = 14 x 1 + 9

We consider the new divisor 14 and the new remainder 9,and apply the division lemma to get

14 = 9 x 1 + 5

We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get

9 = 5 x 1 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 869 and 208 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(14,9) = HCF(23,14) = HCF(37,23) = HCF(208,37) = HCF(869,208) .

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

Step 1: Since 924 > 1, we apply the division lemma to 924 and 1, to get

924 = 1 x 924 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 924 is 1

Notice that 1 = HCF(924,1) .
